 chat we got popped out. Hi everyone, this is Chicho. Welcome to my channel and welcome to the live stream. Today is February 5th 2020 and we're doing our second math live stream drop and tutoring session for 2020 and we've done a few of these in 2019. I'm not sure if we did any for 2018 we might have. I've sort of been live streaming for about a couple of years now. So basically I'm making myself available for a couple hours to answer questions for anyone that it's basically taking high school mathematics but we do a little bit of elementary, we do a little bit of post-secondary but mainly focused on high school mathematics. And we do these once every couple of weeks two to three times a month basically. And we sort of just chill until people show up and it is an open discussion so we do talk about other things as well. Mainly try to focus on sciences and maybe economics and and whatnot. We don't talk about politics and much too much, right? Void, how are you doing? Let's go, yeah. Mathematics, looking forward to this. I've been full-on math mode in January. Just all of a sudden math just kicked into high gear for me with a lot of students and stuff requiring a lot of help. For some reason this January has been the most intense January that I can recall anyway. Let me show you while we wait for some people. By the way if you have any math questions drop them and we'll start dealing with them. If we're talking about anything else we'll stop when we do mathematics. Was just watching 10x10 video on YouTube. Nice. We actually haven't done a 10x10 game for a while so I think it's about time we did one of those as well. Hello, I love Spider-Man. How are you doing? Hope life is wild. You guys, you were here yesterday too, right at the end actually. I remember correctly. Was it you that was right at the end? I think so. I love Spider-Man. Did you go to a comic store today? Dante, how's it going brother? Liquor stream went. Void, I don't know. Right now I'm not feeling the best. I'm still recouping from what do you call it? The flu I got earlier in January, at the beginning of January really, right? So I'm not even sapling the liqueurs, right? Liquor stream probably spring, summer when we start getting some fresh berries and stuff we'll do for sure. Spencer, Iceman, how are you doing? Hey, hope you're doing well. You're doing very well. Thank you. They're literally cooking the books and I... Dante, we knew this, right? We talked about this. And Dante, by the way, since you brought it up, look into who the biggest funder was for that app. I remember there was a discussion on Soros that came up during a political talk, like last month or a couple of months ago. He was the biggest funder for the app they used in Iowa. Like, how hard is it to do a little bit of mathematics and tally up the votes? Really. This is how illiterate our societies have become in the language of mathematics where our education system has deprived people of the ability just to count tally votes that they need a complicated app that most likely is proprietary, right? Funded by special interest groups to count the votes. And then at the end, they flip coin like the way they were flipping coins. If any mathematician, any gambler, anyone that plays games of chance, if anyone flipped the coin the way they were flipping coins, they throw them out of the house. That's not a random toss flip. That's a, oh, I want heads. I got heads. I want tails. I got tails. It's just simple mathematics. If our society, our education system was teaching people mathematics, these kinds of shenanigans would never occur. Never occur. Which is why we're doing these live streams, right? While we're focusing on mathematics. Math rules our world, right? Both in terms of those that understand it and those that do not. Theater guy, Dante, I feel you, brother. I feel you, but I'm not shocked. I wasn't expecting anything else from the from the DNC or the political system. I said from the get go from 2016 when the rug was pulled under, from under Sanders' feet, he should have split, right? Hi Ho Chi Cho, theater guy. How are you doing? By the way, where's the name Chi Cho come from? It's a nickname Spencer. That's a nickname that I had in the 90s and the two nicknames and I put them together and I've been going by Chi Cho since the late 90s online. Playing online games as Chi Cho. Great lasagna. How are you doing? Hey Chi Cho, long time. We'll see. We're a long time, brother. Long time. Glad you could make it. Hunk Mitt. Hello, hello. How are you doing? F, how's life, brother? How are you? Oh, Florida's warm. It's chilly here. That's where I got my cozy sweater on. Same as yesterday. Cozy cozy. Night night. The other day I was working on an engine and I had to do some torque spec conversion. Definitely hurt my brain for a second and felt illiterate. They're working on mechanical stuff and some of these mechanical machines are like the machines in the cars and stuff. They're very specialized. So you have to know what is going on to be able to do the conversions. X, how's life? I hope he learned his lesson and absolutely destroys the democratic party this time around. Dante, I'm with you. But man, if they did that to me, if I was just straight up, if I was playing games of chance, like may it be just regular car games for no money or was gambling. If anybody pulled that crap, man. What? Lurky. It's easier to, lurky. Ah, okay, cool. How do you, lurky? It's easier to pronounce. I can't even connect the lurky. Lurky, welcome to our stream. Beans, how's it going? So from a kg to pound, night night. Kilograms to pounds. Is that what you were doing with torques? No. Is that the conversion? Torque spec conversion. Pounds of pressure? What the, the one car that we used to have as a family relative had it was an RX-7 that had a torque engine. That thing was powerful. What a kick, right? I joined yesterday and it is lurky because I lurk a lot. Ah, okay. Okay, lurky. I'm glad you joined. I'm glad you're back for a second day. Different type of stream, I guess. We're doing mathematics. Pounds to kilometers? It can't be pounds to kilometers, is it? Night night. It must be pounds to kilograms. Pounds doesn't go to kilometers. Pounds is weight, kilometers is distance. Nope. Kilograms, kilograms. It's got to be kilograms. You have to convert to the same type of unit. That might be the problem why it was hurting your brain. That sounds more like a ratio. Eagle units, freedom units. Eagle units to freedom units. Foot pounds to meter kilograms on a Japanese motor. What? That's cool. Oh, I guess so. Foot pounds to kilometers. Should we do the conversion? By the way, this is the way you could do the conversion. Brain cannot convert. Watch this. Let's say you want to convert from feet pounds, right? Feet pounds. The way I do it, if there's a conversion like this, you write out your original conversion. Sorry, not kilometers. Not kilometers? Okay, so the top, what you wrote down is correct because feet is distance, pounds is weight, and you're converting to distance over weight. So that works. Find a linearization of function. I don't know what linearization means. I think you're talking about the tangent, right? Beef. Are you talking about the tangent? Because the terminology changes from different parts of the world. In my part of the world, if there's a function like this, and if you try to find the, I guess, linear function at a 0.42, this is the 0.42, you would be looking at the tangent line, right? I'm not sure if I could do that. I'm not doing calculus right now, right? But if you're doing unit conversion, you want to go from foot pounds to, let's draw this, and we take it out. Kilogram, kilometers per kilogram, right? If that's a unit conversion you want to do, that looks like a sine wave. Is it a sine wave? 1 plus 4x. It's logarithmic. X, Y. I definitely don't know how to do that. Take the derivative of that, the calculus. That's beyond me right now, right? So if you want to do this, what you want to do, basically, I'm just going to ban this guy. I can't even highlight these things properly. Did I get it? It's tangent. It is tangent. Brother, you're out. Like, at least, at least come and chill a bit before you drop bombs, right? Alternate current makes a sine wave on an oscilloscope. Okay. Yeah, it's tangent planes. Yeah, it's tangent planes. So if you want to convert from this to this, you want to take the feet and convert up to kilometers, right? So the question is, you want to get rid of feet. How do you get rid of feet? You get rid of feet by putting feet here. Now, can we go straight from feet to kilometers? Usually not. Usually you convert feet to, I mean, I could do a multi-step, but there's got to be a conversion from feet to meters, right? That would be a natural conversion. Yes, squiggly line. Can you guys stop math flexing? I feel stupid now. Me too. I don't know how to do that night night. It's beyond my math, right? So if we want to convert this, the feet is going to kill the feet, but what are we going to convert the feet into? So you write it as ratios, right? Now, I can go by memory pounds. I can't go by memory into grams. I don't know what that is. I would have to look it up, right? If you guys know, feet goes into 12 inches, and I know what inches is into centimeters, and then centimeters, we could go to meters, and then meters would go to kilometers. That's a long-ass way of doing it. But one feet equals 0.3048 meters. Perfect. Thank you, beans. So one foot is equal to 0.3. Yeah, the 2.54 I remember by memory for some reason. 3048. Here, let me erase this. Make some room for us. So this is 0.3048 meters. So we're converting feet to meters right now because the feet kill the feet, so we're in meters. But we don't want meters. We want kilometers up top, right? Say, I have to look up the meters. Yeah, the meters I never remember. So we want to convert meters to kilometers. So that's a straight conversion. We could put meters here, and we could put kilometers here. You can just put the units and then look up the conversion. But meters and kilometers are easy. One kilometer is 1,000 meters, right? Here, we'll put 1,000 meters. So meters kills meters. Now we have kilometers up top, and we've got kilometers up top. Perfect. Now we're going to convert pounds to kilograms. I don't know what the conversion is for pounds to kilograms. Should I write this a little cleaner here? We'll make a little bit of more room. Feet over pounds, oops, that's not a one. That's just pounds, pounds times. 0.3048 meters over feet, and then feet kills feet, and then we're going to go meters down here, kilometers up here. One kilometer equals 1,000 meters, right? Now we've got to get rid of pounds, pounds. What are we going to convert pounds into? What's a good conversion to pounds? One pound equals, oh, that's easy, 0.45. So zero point goes straight to kilograms, right? 3592, 3592 kilograms. So pounds kills pounds. We've got kilometers over kilograms, which is exactly what we needed. So all we've got to do now is do whatever is being told us to do here, right? Math is like push-ups. The more you do, the better you get. Yeah, 100%. So in the top, we're going to have 0.3048, oh yeah, this meter is killed, this meter is too, right? Kilometers over 1,000 times that, you just move the decimal place three over. So 453.592 kilograms, whatever that ends up being, right? And by the way, this is feet per kilogram per pound. We would assume this is one, right? But whatever number you had here, whatever your x was, your x would be here, right? So this x feet pounds would be equal to x kilogram, kilometer kilograms. That's a weird unit. I don't think I've ever done kilometer kilograms before. I don't remember. I must have done it during university times where we're doing calculations, but this unit is not familiar to me. I've never really used it in doing geophysics or anything. We must have done it at university, but I never dealt with it again in my work, right? Where and when would you use a kilogram? I'm interested. From the sounds of it, they're using it, the night night was using it for an engine for torque conversion to calculate the, where is this comment? The other day I was working on an engine and I had to do some torque spec conversion. So torque spec conversion kilometers per kilogram. I don't know. Like, I can't wrap my head around it. Kilometers per kilogram. I don't know. I don't know. I would have to look it up to see where it's used. Ohm's law is where I learned my math. Ohm's law, yeah. I didn't use kilometers per kilogram. I'm mistating the units. Oh, are you mistating the units? So this might not exist. We don't know what this is. This is, this is the answer to the unified field theory. Kilometers per kilogram, right? I'm so used to the good old red blooded freedom units, freedom fries, right? Let's kill this guy. But any conversion you can do this way, right? Any conversion. And unit conversion is ridiculously powerful. The answer for every question is 42. I thought it was 420. It's freedom units miles. I don't think so. I think he's being funny. Freedom units is kilometers. Freedom units is kilometers. I don't know what freedom units are. Freedom units, man, we could go into the political realm on that one, right? We could go anywhere with that one. Sorry. An Eagle unit, it's miles, right? An Eagle unit is miles? I don't know. I've never heard those. The only place I heard freedom units would be freedom fries, right? Sorry, I was trying to tell you that I was not sure what the unit I was converting from. Oh, you didn't know what the unit was converting from. But was it kilometers over kilograms? The final units you had? Freedom units are all units that are not US units. Oh, so metric or SI units, the international units because I do not understand. If X is the measure of an unknown entity, then isn't everything bound to the laws of time and relativity? If X is the measure of an unknown entity, then isn't everything bound to the laws of time and relativity? That sounds like a rap rhyme, right? Lyrus. Are you a lyricist? Lyr-Winio? If X is the measure of an unknown entity, then isn't everything bound to the laws of time and relativity? Everything, no matter what, is bound that we know of in the material world, is bound to the laws of time and relativity, for sure. That's an opinion. US units are Eagle units. Yeah, I was joking. I needed to convert the unit to feet per pound, ended up using a chart in an obscure manual you found on a farm. Wow, fun. Yeah, there's so many charts that just, like I know for nursing, there's conversions that a lot of, in the medical industry, there's a lot of unit conversions they have to do. It's just punching the formulas and they get something out, right? It becomes automatic, but if someone does the miscalculation, there's serious repercussions. A lot of, there's a tremendous number of deaths and harm done in hospitals with people doing a mistake in their calculations and giving the wrong dosage to a patient, right? Like, we're talking into the hundreds of thousands, right? In the United States anyway, I've looked at those numbers. So there is, and those are just the deaths. Just imagine how many emergency, I forget what the light code is that they announced in the hospital is, for giving the wrong dosage to someone, right? It could be serious. Ultimately, I was just trying to tighten a bolt to the right torque spec. There was a lot of effort for just a couple of bolts, but I guess it's important. It is important. Yeah, torques, there's a tremendous amount of kick to end torque engines. That's, that's what gives them the power, right? Like, I don't know if any of you guys have ever driven a car. That's a torque engine. I don't know. I don't even know who makes torque engines anymore. But back in the day, in the 1980s and 90s, there was a car that Mazda made. It was an RX7 and it was a big engine, heavy engine, really heavy engine. And when you put your foot on the gas, the whole car, you could feel it go go, like there was a torque to it, right? And it was a solid engine and it was a really good car. It was a sports car low. And I actually, I'll tell you a story. I actually hit a deer going at 120 kilometers per hour, 120, 130 kilometers per hour on the highway with an RX7 with a torque engine, right? In 1988, I believe, 8890, right? We were lucky. I was driving, it was a passenger. And by the way, here's a recommendation or advice. If you're driving, if you see one deer, keep your eyes on the road and slow down because deer travel impacts. So if you're driving, you see one deer, slow down, not, you know, don't slam on the brakes because there could be cars behind you. You don't want to get rear-ended, but slow down, put on your blinkers, right? Slow down and pay attention because deer travel impacts. What happened with us was we were driving and the sun was coming down. And deer, they move during sunrise and sunset, dawn and dusk. There's a lot of movement, right? So be careful during those periods, more than anything. Well, be careful all the time, but pay special attention during those periods. So the sun was, we're going through trees, so it was like dark shadow light, dark shadow light. And we saw three deer on the side. I looked over and then I looked ahead and there was a gigantic deer in front of us, right? Going on 120, 130 clicks an hour. Hit the deer. The deer flew up its head, hit the roof. We know because I heard it and it indented the roof, right? The deer took a flying, flew like, I don't know, how far, right? We were lucky because the RX-7 is low, right? It was a sports car. If this, if we're driving a car that was higher, the deer would have gone through the windshield. And that's one of the times where animals, if you hit them on the people that hit animals on the highway, the animals fly through the window and usually end up hurting people badly or killing them, right? So we were lucky. We're driving a small car. Going fast enough that hit the deer flew up and by the time he was coming down, we're already under it, right? Went off the highway, came back and the deer was like across the median on the other side and he was struggling to get up. And actually, no, no, no, my mistake. He was struggling to get up because I stopped, looked, the deer was already on the other side. He was struggling to get up. We kept on driving, came back. On the way back, the deer was already dead, right? Went to the small town, filed a report with the police and it was on my way. It checked us out from Vancouver to Toronto, right? Across Canada. So I only got to Hope. If you know that distance, it's like a couple of hours of driving, two or three hours of driving. And we went back and parked the car because we couldn't even lift up the herd. It was damaged inside. We're lucky to get home. And the next day, a car was dead. We had to tow to the, what do you call it, the mechanics to get it fixed, right? This is a fun one. If you have 2,000 debt to a credit card, how much interest do you pay a day if your ARP interest is 15%? Are you paying 15% cumulative daily, I guess? We can figure that one out. Just recently, there was a guy in my area who hit a deer and it went through the windshield and killed him. Yeah. And that's the main injury that people get. The answer is 82 cents, if I'm right. Let's check it out. So you got $2,000 of debt. And 15% interest, right? ARP. I don't know what ARP is. ARP and you're, you are, I guess that's supposed to be R. Where's P, P, R, maybe? I'm assuming that's going to be credit cards. You're paying 15% on credit cards. That's on the cheap side. I don't know people who are paying like 28% of the credit card annual interest. They say, oh, okay, annual interest here. So annually, that's cheap as well, right? A lot of credit cards are daily or monthly at least, right? So let's assume it's annual. Okay. I always use the formula, this formula. A is equal to P1 plus R over NNT, where this is the principle, principle. What you start with, start with, what you end with, end with. This is the R is the rate of interest. That's that guy. T is your time in years. And N is the compounding period. Compound. And this is time. Okay. Compounding period for us is one. We're going to do one a year lurker. So it is true. 82 cents, if I'm right. Okay. 82 cents. Let's check it out. What should we do? I mean, you could just figure out what 15% is. You don't even need this formula, right? You could just go 15 times that. I think so anyway. So 15 times 1,000 is 150 multiplied by 2. So $300 interest. I think so. $300 interest, right? That you're paying in one year. Divide that by 365. Don't even need that formula. Right? Let's check it out. Yeah, that's what it is. Okay. I don't even need this formula. I always use this formula. Write it down and then look at the question and go, no, no. We don't need this formula. We can just do it this. Right? I divided point by this times the principal balance. Yeah. Yeah. So 300 divided by 365. Let's make sure that's correct. 300 divided by 365. And right now we're in a leap year. So it should be 366. So 82 cents and yeah, 82 cents, 82.19 cents per day. You're paying interest. What you could do as well is figure out what it would be if you were compounding. So 82.19. Right? So the answer was 0.8219 cents. Let's figure out how much interest you would pay at the end of the year if you were compounding daily. Right? Because usually if you don't pay off your balance at the end of the month with a credit card, they charge interest on your total balance, all of it, I believe, for that month. Right? So I don't believe they're doing it daily. So this would be, n would be 365. So let's figure out how much total you would have if you were doing this. So you would go A is equal to 2001 plus 0.15 over 365 to the power of 365 times one, one year. Right? So what would that be? Let's just do this. 0.15 divided by 365 is that plus one is that to the power of 365 to the power of 365 is that times 2000 is that. So your total you would owe them if you were compounding daily is 3, oops, not 3, 2, 2,323.50, 60 cents. Right? We're round up to the decimal places. So 60 cents. Right? That's 2000, by the way. 2,300. So subtract these guys. That minus that is $323.60. Right? We figured out this one was $300. You would pay if you were compounding yearly. So if you divide this by 365, right, minus 2000 divided by 365, you'd be paying 88. So you'd be paying if it was being compounded daily 0.866 cents per day. Right? So you're paying 6.7 cents more per day if it was going to be compounded daily. Right? Big difference. The banks make billions of dollars by changing the terms of interest payments from yearly to daily. Right? If the balance changes every month, you would have to calculate out each month. Yeah, you would have to calculate out each month, of course. We're going on a simplistic realm saying that, okay, you're not paying anything. Right? Because the principal balance changes every month. So the debt increases. Yeah. Going to head out, okay, night, night. Have a great day. See you chat. Hope you have a fantastic day. And if you can make it tomorrow, coronavirus virus, and we're going to do mathematics, by the way, again. I've got some charts, tables set up. I got to clean up the table a little bit. I'll try to get it as clean up as possible for tomorrow night's stream. But we're going to look at some data because in the last mass stream we did, we talked about the exponential growth of the coronavirus at the beginning stages anyway. That was like last week or I guess it was like 10 days ago. Right? Tomorrow night, 8.30pm. Right? We're going to do 8.30pm. And we're not going to be here. We're not going to use the board. I'm going to have images popping up. I might bring a tab and do a little math, but I don't think so. I think I just want to present some of the data. 8.30pm Pacific time. Yeah. Yeah, my time. West Coast, Canada, the United States. So I know it's not going to work out for some people, especially some of the people in Europe because they're eight, nine hours ahead. So that puts them like four or five o'clock in the morning. Right? That's early in the morning to look at the mathematics of the coronavirus a little bit too early possibly. Right? So, but we'll have it up at some point as well. Right? Within a few days. I'm six, eight hours ahead. Yeah. So that's going to put you like 2.30, 4.30am. Yikes. That's early. Should I show you the snacks that I brought? I got some cuckoo and avocados and cuckoos I made. This I made like three days, two days ago. So this is the third day we're eating. It's fantastic. All right. Have we got videos out on this? How to make this? Eat your greens. 5.30 for Europe, 4.30 for UK, and some others. I'm originally from Iran. Yeah. I was born there. Lar, Lar, Winio, Lar Winio. No worries. I'm just about getting used to the time difference here in UK. My old flatmate has just moved to Victoria. Victoria, Canada? BC? Where I am? That's cool. From the UK to Victoria. What a diff. What a diff. Actually, not that big of a, no, big diff. But there's a lot of UK influence here. All right. I also have some tea. What do you call it? Halva. A little bit of sweet. I mean a little bit of sugar kick as well. It was good. And I got some ginger. Mask of raven. How are you doing? Ginger, black tea, ginger with honey. That's why it's murky. It's nicer, man. It's very chill. It's very chill here. West coast of Canada is on the download to a certain degree, except Vancouver. Vancouver's gone crazy. Just with the influx of money and stuff going around and whatnot. It's become sort of a transient city, tourist city. So it's changed a lot. But we'll see how long that lasts. But it's a nice place to be. Lots of nature. Amazing nature. Mask of raven. We're doing some calculations. By the way, mask of raven. Mask of raven knows its math well. Is there any place where you use units of kilometers over kilograms? Like in tort calculations for what do you call it? Which part are you from? UK. So we just did a conversion of feet pounds to kilometers per kilogram. So I'm assuming feet pounds is the pressure on the engine for torque engine. Feet pounds. How many pounds of pressure there are per square foot for torque engine, I guess. Is it a rotary engine, I guess? Foot is a unit in figuring out horsepower. So would this be equivalent to horsepower? Horsepowers is foot per pounds? Is that what it is means? I've never come across this. I don't think so. Foot pounds, feet per pounds, I guess. I think I remember this. This I don't remember at all. So horsepower is not foot per pounds. This is the amount of pressure that would be, like if you're, if you go in the water, right, if you go deep sea diving or whatever it is, submarines, you would have to calculate how much pressure there would be. How many pounds of pressure there would be per square foot, I guess. Don't know exactly what we're figuring out. I don't know either. London. Big life plan is to be out west coast Canada in the next few years. Awesome. It's nice here, man. I like it. The metric equivalent of a foot pound is a Newton. A Newton meter. Newton meter. Really? That's what it is. It's a unit of work. Kilogram, kilometers per kilogram is the equivalent of foot pound is a Newton meter. The metric equivalent of foot pound is a Newton. Wow, this is a Newton? That's a Newton. Newton is meters, oops, Newton is kilograms per times meters per second squared, right? Kilograms meters per second squared, yeah. It's kilograms times, kilometers times kilograms. Really? Foot pounds is this. So we definitely wouldn't convert to this. That doesn't make sense. A Newton meter. So it's a Newton meter on Newton times a meter. So it'd just be meters squared, wouldn't it? This guy? No, the pounds is in the bottom. I don't know. This stuff confuses the crap out of me. The imperial system just confusing for me. In Canada we switched from imperial to metric a long time ago. Dante? Yeah, it doesn't sound right. Because the weight is in the bottom here, but it's in the top there. So that doesn't make sense. I know Newton's is that. Newton meters would be, oops, take out the squared. So Newton's meters would be Newton meter would just be that times meters, which would be kilogram times meters squared per second squared. And meters per second squared is just acceleration. It's like a joule, right? I guess so. Yeah, joule is, oh, I forgot my joules. Joules and Newton meters? Is that what it is? I forget. I wish I was teaching more physics students. I wish I had more physics students, so I'd be sharper on my physics, which I'm not. I go through waves when I teach with the type of students I get. Sometimes I get a lot of physics students coming in. We do a lot of physics, a lot of calculations, sometimes a lot of mathematics. Sometimes it's both, right? So again, keep in mind, if you're struggling with mathematics, struggling with learning physics, chemistry, any type of sciences, or anything in general, just keep in mind that if you don't practice it, you lose it, right? A foot pound. Oh, foot pound. This is foot per pound. So foot pound. That's what it is. Foot pound, not foot per pound. So we take this off. So foot pounds takes you to this guy. Takes you to this guy. This guy takes you to this guy. A foot pound is a unit of work. The metric equivalent of which is a Newton meter measured in joules is foot per pound. No, it's still per pound. What? Okay, so is that wrong? Doesn't go to this? One joule is equal energy value of one Newton meter. Okay. Units. Oh my god. That's one of the, by the way, just to let you know, it's foot times pound. Yeah, it shouldn't be divided by, I keep making mistakes. Damn it. Oh, Raven, you're throwing me off. Dante's on it. Capital letters. That's the same thing you're using for I want capital letters. Yeah, I would be too, Dante. If I wasn't expecting it, I was expecting it, right? Their corrupt system is corrupt. You can't, you can't, like, fool me once, shame on you, fool me twice, shame on me, fool me three times, I'm a diggling, fool me four times, what the hell, fool me five times, I give up, fool me six times, what am I doing here, fool me seven times, oh, let's try it again, fool me eight times, like how many times, fool you how many times, until you say, I'm out, right? For me, it's once, right? 2000s in, done, out. Mathematics, back to mathematics. No more politics. Back to mathematics. What else should we do? What else should we do? There's lots of, what do you call it, the whole, in my part of world, anyway, the whole education system has been shifting a lot in the last five years. There's just with, in the last 10 years, really, with access to online and stuff like there's, there's some school districts that are dropping ridiculous amount of money to buy automated systems for, to manage kids, and they're cutting back on their education, right? And they're telling kids to have their, you know, the resources are available online. We built this thing to help you, right? But they didn't have to spend millions of dollars, tens of millions of dollars to build this thing for kids to use, because majority kids don't need that, right? They need to, they need direct interaction, direct education, right? Direct stimulation, which is crazy, which is crazy. But it's actually not just foot pounds, it's pound force, feet times pound times feet, so it's feet squared. Is that what it is? Pound, it's pound force times, force pound. Man, one thing I had a hard time with when I was going to, when I was in high school, is doing, that I found very difficult when I was studying chemistry and physics, because I didn't understand the systems that they were converting from, from this to that, from this to that. Oh, Dante, so it's pound force. So pound force is feet times pounds times feet, makes no sense if it's pound. That's just mass, yeah. No, pound force times feet, aka pound force times feet. I didn't realize there was something called pound force. So pound force, pound force times feet, oops, feet, and the abbreviation for it is lbf times feet. Wow. I, I don't think I've ever seen this before. I don't think I've ever dealt with this before. And that's the problem a lot of people encounter when studying physics or chemistry. For some reason, our current education system, in my part of the world anyway, like for example, grade 11 physics, they, if you grab a grade, the imperial system, oh my, oh my, the, if you grab a grade 11 book in my part of the world, and the curriculum in general, they try to cover all of these different types of disciplines in physics in one year, one course, right? So kids start off with kinematics, right? You got, here, let me give you the lowdown on this. They, they do kinematics, which is basically, here, let's just write it down, kin, kin, kinematics, and then they do dynamics, and then they do statics, okay? And then they do forces, forces, and then they do gravitation, gravity, okay? And, and the list goes on. So each one of these units, each one of these disciplines has their own formulas, and their own units that you have to calculate, and they do energy, energy, energy, and momentum, momentum, right? And just continues. So you have to learn all of these units without really understanding what they represent, and do all these calculations, all these conversions, solve all these problems without really understanding what's going on. And people say physics is hard. Physics is not hard. The way they're teaching it makes it difficult, right? If they want to teach physics properly, they should break all these up, group some of these things together, and teach them in separate years, really focus down on them, right? Always start off with kinematics, right? As soon as you get into quadratics, one of the reasons they don't start kinematics until grade 11 is because the math curriculum is so far behind that in my part of the world anyway, they don't talk about quadratics until grade 11, right? So you can't teach it earlier, right? If you can teach it earlier, start, you know, forces. You don't need quadratics. You could do, you could do statics before you learn quadratics. You could do energy to a certain degree, right? How are you? Do you like riddles? From a complete pack, from a complete pack, we'll read this. It looks like math. I was scared. It might be a trolling factor, right? From a complete pack, a small number of cards has been taken out. If you deal among four people, three cards remain, okay? If you deal among three people, two cards remain. And if you deal among five people, two cards remain. How many cards are there? Let's lay this out. I'm not sure. Let's check it out. So how will we approach this? So we don't know the number of cards in the deck. Let's call it X. That's the number of cards we have. From a complete pack of small card, a number of cards has been taken out. From a complete pack, a small number of cards has been taken out. So you take a whole bunch of cards out. If you deal among four people, so are you dealing out the what you took out of pack? So I'm assuming X is the number of cards. The first sentence is just throwing you off. If you deal among four people, three cards remain. So basically, if you take X divided by three or four, divided by three, mask of Raven does it. So let's check it out. Let's see if we can do it. So I'm going to approach it this way. I don't know if it's the right way. I just like laying it out first. The most simplest way I can. If you deal among four people, three cards remain. So if you divide this by four, you're going to get a number with a remainder of three. If you take this and divide it by three cards remain. If you deal among three people, two cards remain. And if you deal among five people, two cards remain. So three people, you get the number r is equal to two. And if you divide it by five, you get the number r is two. The remainder is two. So what's the best way of doing this? 47. Mask of Raven. How do we do? How did you get it so fast? Literally. I like reading riddles, thinking about it quickly, and then looking at the answer. That's the way I like doing riddles. I don't really do them. I read them. Right? So how do we do? What's the best way of doing this? Mask of Raven direct us. So if we divide it, so basically here, if you say the remainder is three. So this would be three over four. This would be two over three. And this would be two over five. Right? Whatever the number is. He's right. 47. Well, the number is an equation is a multiple of 15 minus two. Notice that first. The number in the equation is 15 minus two. Is it? Plus two rather. Notice the first. Mask of Raven. So let me see. Well, the number in question is a multiple of 15 plus two. Is a multiple of 15 plus two. Oh, because of these guys, right? Because there's two there. Cool. Multiple of 15 plus two. And then how do you deal with that? So it's a multiple of four plus three. Ah, that's a cool way of approaching it. I don't have a riddle mind. I don't. It takes a certain mindset to do riddles. So basically what it is here is to get X. Well, here, let's do it this way. Let me erase this. X, right? If we multiply everything by five here, you're going to get X is equal to box, oops, five times box plus two. This is the remainder theorem, by the way, when it comes to polynomials. If you know your division, polynomial, long division, actually it's just long division. It's what do you call it? It's just a remainder theorem, right? This one would be X is equal to box plus two. And this one would be X is equal to four box plus three. If I did that correctly, I used my modular arithmetic. I used modular arithmetic here, but the way you're doing is a good intuitive way to think about it also. My chat got deleted. Can someone post a question again? Yeah, I didn't see your question here. Let me grab it. Here's the question. So prime, litter, litter, prime posted the question from a complete pack of, oh, thank you for posting it. Little, little try. Oops, that's okay. So, so far I've gone to here. How would we go from here to 47? How would we go from here to 47? We could subtract the equations. We have three equations. We got two unknowns. We should be able to do this, right? Or, wait a second, these are different. These are different. This is, let's call this Y, Z, W, right? So, right now we've got four unknowns and three equations. We need one more equation to be able to solve this as far as I see it, right? Because we don't know what the numbers are here, right? These boxes are different. Let's call these Y, Z, W. That's what we're calling it. Okay, or I'm calling it Y, Z, W. Y, Z, W. Oops, then this is, I wrote this backwards. So this would be W, Z, Y. Just to confuse you guys, I flipped it. So is there any other relationship we have that we can figure out? Because we've got four unknowns, three equations. In mathematics, if you have four unknowns, you need four equations to solve it. This is five blank plus two, and three blank is two plus two, or both plus two. You can combine them in one equation, 15. But the blanks are different. Z and Y would be different masks of Raven, wouldn't it? It would have to be, no? Then the number of equations is reduced. But the Z and the W are different numbers. It's like a five blank plus two, and three blank plus two, or both plus two. You can combine them in one equation, 15 blank plus two. So you're multiplying them two times. Two cards remain. Combine those two guys. So are you multiplying them? I don't follow the logic there. So three times five is 15. Sure. Like if we multiply these, then the blank becomes WZ. W times Z. But then that becomes four. So I don't understand why three blank plus two and plus two are both plus two. You can combine them in one equation, 15 blank. I don't see it, to be honest. I don't see it. I mean, the only way you get 15, if you multiply those guys, and if you multiply this, you get an X squared, and that one you got. But you can't just multiply these guys. It doesn't make sense. Unless you foil it out, or you don't want to foil it out. No, I don't see it. Well, riddle me this, riddle me that. Gicho doesn't know the answer. What did Mask of Raven do to figure it out? He did modular. I use modular arithmetic. I don't know what modular arithmetic is. Modular arithmetic. Nice question. It's got to be a way around. Yeah, I don't know. I don't know. If someone does know where to go from here, our Discord page would be awesome to post it up, right? To see where it takes us. I don't get it either. I don't get it either, Dante. I don't know how you would combine them to get 15. Let me look at subtract them, get rid of the X's and those guys. Oh, the relationship we could have would be this. If you just subtract the equation one and two, let's see where that takes us. X is equal to 5W plus two and X is equal to 3Z plus two. Subtract this from this, right? So equation one and equation two, subtract them. So this kills this. This becomes zero. This becomes 5W minus 3Z minus 3Z and the two kills the two. So we have this relationship. How's that going to help us? I don't know if it is, right? So 5W is equal to 3Z. Did you try that too, Dante? Modular arithmetic is using remainder, but I don't know how that's relevant. Oh, is that what it is? So that's exactly what we're doing. So over here, here, let me erase, give us some more room here. So over here, we would just have 3Z is equal to 5W, right? But that's just combining these guys. We need an original equation. Hi, been lurking, but imagine you take those two remainder cards away and you get a number of cards divisible by both three. Oh, so they're for 15. Also, not sure if that's helpful. That is helpful, Mr. Because what it is, oh, that's, of course, we can't just think of it as a standalone thing, right? Are you laughing? Is that what it is? If, of course, of course, didn't even think about it, right? Crazy. If in both scenarios, two cards remain, the amount we look for must be a multiple of three, and it must be a multiple of five. So it must be a multiple of 15 as well. That's right. Crazy. I can't believe we didn't think about it. So if you zap this out, then they must be this. So if it's a multiple of 15, so there's got to be two remainder. So x is equal to 15 blank plus 2. So how did you get 47 then? So the blank is 3, 40, 45 plus 2. But how do we narrow it down to 47, right? How do we narrow it down to 47 to 47? It's a small amount of cards that took out all from a 52 deck. Is that what it is? All good with you, bro. Hey, Nicholas, how are you doing? Justin from, yeah, all good, brother. Thank you very much. By the way, Nicholas, check this out. My snack, one of my snacks for today, cuckoo and avocados. Cuckoo and avocados. All right. Super delicious. I made the cuckoo like two days ago, so this is a third day. I'm just eating it as snacks. Very good. This combination is fantastic as well. So there's only three options. That's right. We narrow it down. It's by elimination. It's by elimination because if it's got to be divisible by three, multiple of 15, the only choices is there's either 15 cards, 30 cards, or 45 cards. Right? So if it was 15 cards and there's two cards remaining, so that's 17. If you divide 17 by four, you get a one remainder. So it's not a three remainder. If it's 30, you add two. That's 32. 32 divided by four is straight up eight. So there is no remainder. If it's 45 plus two is 47. 47 divided by four is 11 and three over four. That's the three we want. So it's got to be 47. So it's by elimination. That's the riddle part. Right? You have to eliminate great question and great collaboration trying to solve it. Awesome. Now that's a snack. Now that's a snack, Nicholas. You should try lemon juice and pepper on your avocado. Oh yeah, lemon juice. Yeah. Right now I'm staying away from peppers, so no peppers, but lemon juice for sure. And if lemon juice would go, what do you call, amazing with the cuckoos as well? Chat is amazing. Little tribe for sure. We've got a nice group of people here, man. Thank you. Thank you. And thank you to everyone in the chat. It's fantastic. Don't make, don't make this is a great question. That was a great question. Why are we wearing it? Wearing a tuk. I'm staying warm. Also no bell peppers. Bell peppers. The red ones are okay. I like, I don't mind eating the red ones and the yellow ones are okay. The green ones, hard and the tummy. All right. This was a great question. This was a great question. And I like doing the remainder theorem laying on it like this because you get a visual sort of, it's just ratios, fractions. Glad I could help you entertain us for sure. And you guys too and educate, we're learning, right? Fantastic. There's nothing better in life really. Well, there are a few things that are really awesome, but one of the great things in life is learning while being entertained. Like I'm munching on cucko and avocado. A great question. Great question. I liked it. I couldn't do the jump straight to this. It didn't make sense to me, but it had to be a multiple of 15 with the two. Yeah, it made sense. The variables threw me off. We have three equations. And then you, the way you solve it without the fourth equation, there's only three choices. And you reference going to show this to my students tomorrow. Awesome. Mr. Moss. Yeah, for sure. Great question. Great question. And you don't need high level mathematics, really. You need to know long division. Remainder theorem would be good. That's sort of grade 11 in my part of the world. So you would have to explain the remainder theorem to people to say that you can lay out the problem like this. Right? Fantastic question. Nice. Very good. And Nicholas. I got a little hall of eyes as well. Little sweetness. Tahini and sesame seeds and sugar. I need the sugar. Fun. I like these math streams. Math dreams. What did we do today this week? We did politics or current events, relationships, mathematics. Tomorrow, coronavirus. We're going to look at the mathematics, the growth rate of the coronavirus and the data I'm grabbing some of the stuff from this website here. Let me give you the link for it. I've started tabulating some stuff. Hopefully the link works. Sometimes I have to refresh it to get the data for the coronavirus. And rig it, sort of go to the original source, the original website, and then refresh and do a couple of clicks and get it back up again. On the plus side with the coronavirus, the graph is going linear, right? So hopefully what we're going to see with another math riddle. What did 20 do when he got hungry? What did 20 do when he got hungry? He ate one. Working for me. Working for you also. What did 20 do when he got hungry? I don't know. What did 20 do when he got hungry? 28. You could do that for all the 10s. What did 30 do when he got hungry? 38. You could follow it up with another question. I got to remember this. I got to remember this. We use it on some of my students. They'll get a kick out of it. So we graphed the coronavirus before, right? And we had a graph like this going exponential, and we extrapolated saying if it was growing exponentially, if it continued growing exponentially, it was going to be insane. It is still insane. Well, I heard seven, eight, nine. Seven. But what we started getting was it went exponential, but now it's sort of linear. And hopefully we're going to see it start rolling over into an S curve, right? S shape. We don't know yet. We've got two more days of data. I'll try to get the data for Thursday as well. I'm not sure if we'll have it for Thursday, but I should be able to get two more days of data in there. There's two more extra points that we can graph. And hopefully that's what we'd like to see. Cases outside of China are actually doing this now, right? But we don't know yet. Only place I'm worried about regarding India and Bangladesh. India, India is the one, don't it? Because they couldn't have, no, no. India is the key. I agree with you, right? There's only so far three, three that we know, but like really, once it goes in India, if it expands there, they neither have the, well, they do. They would have to. But if there are vaccines available and stuff like this, they would have to start en masse. But hopefully it doesn't. Hopefully it doesn't. But I'm not too optimistic that it's not going to grow. We might get a linear and then like this. Just on that, no, an exponential. I'm not sure if anybody's following the markets, but we have one of the greatest short squeezes in stock market history in the last month. Okay. One of the greatest short squeezes in stock market history occurred in the last really two to three weeks, right? And that was with Tesla stock, right? So Tesla, for a while, if we do a timeline, whatever, the graph was doing this, it went up to 300 and it collapsed now to $1,770, right? And it stabilized. It wasn't going down anymore, right? Eight years ago, it was at $25, right? So we're not mapping that. So let's assume this is our $170 mark here, right? And then it started going up, started going up. This is what you see in the markets where you get a short squeeze. And a short squeeze is people who are betting that a stock is going to go down and the stock goes up and keeps on going up. And they basically get margin calls or they start covering their shorts because they're losing too much money. Start, stock, start going up, start going up, start going up, start going up, and went like this, right? Hit almost $1,000, almost $1,000, right? The timeframe we're talking about here, it was like five months ago or so, but basically from here is the key, right? Because this is going exponential. And this was in the last couple of months, two months, two to three months, two to three months, right? This movement here was in the last, like a week, right? That went from like $500 to $1,000, right? Hit a $980, like yesterday and today it dropped 160 bucks or something, 150 bucks, so it did this, okay? So those people who were shorting it up got really burnt. And this is basically, it went exponential on a log, semi log scale, right? And once it does that, I don't want to say guaranteed, this is not financial advice, this is not trading advice, this is nothing. I don't play this game no more, right? But once something goes exponential on a semi log graph, it's a pretty safe bet to say it's safe to short it, right? Not 100% safe because when this was 750, I told people I wouldn't be long on it, I wouldn't be short on it, right? So this part was one amazing short squeeze. Hello, I'm back. I love Spider-Man, how are you doing? How's life? Welcome back. You took off, you took off doing a math riddle, man. We got two of them. What did 20 do when 20 got hungry? Let's do some math. I love Spider-Man. What did 20 do when 20 got hungry? And 30 did the same thing, and 40 did the same thing, and 50 did the same thing. They all did the same thing. What did they do? My stomach is growling. What did Chicho do when Chicho got hungry? What do you do when you get hungry? And then the other one was cards. I'm not sure. 28, and then 38, and then 48, 58, 68, 78, and Chicho ate. Can we create a horse racing problem? The eight. What did they do? The eight. Yeah. Horse racing problem. Have you guys ever played a horse racing game? I'm reading a book about anti-gravity, anti-gravity. That's cool. It's impossible to put down, really. I know that. I've heard some theories that anti-gravity has been around for a while, right? Since World War II, if not pre-World War II. That joke's from Chicho. Funny. Oh yeah, a little trial. You can't post links on our chat, just because when we started getting on Twitch, we had a lot of trolls come in, like all other people. So we didn't want any clickbaits. But we do have a Discord page. Here, Discord. Discord. And we have a folder for heavy books and light books. I think I switched the name. Call them books, light books, heavy. Please post a link there, and we'll check into it. We have a lot of people on our Discord and pop in here that we do enjoy our books, right? And I do have a book reading club playlist on my YouTube channel. Sort of a book club, I guess. I think I called it a book club. We'll read some books and talk about some books. But anti-gravity is cool. I looked into some of it in the past. Tesla is... I don't know if it was Tesla related. It was something else related. I can't remember what it was. But there's a racing game, horse racing game that you can play, right? If you have a deck of cards, okay. And this, this you can do. And like, what do you call it? You can do it with friends and family and stuff like this, right? Lay down the cards, right? So make a track. So take cards, lay them down. Make whatever track you want, right? So all these are just cards, right? And face them down, right? Here's a riddle. Let's check it out. Suppose you walk past a barber shop one day and see a sign that says, do you shave yourself? If not, please come in and I'll shave you. I shave anyone who does not shave himself and no one else. So the question is, who shaves the barber? Himself. So this has got to be a gender thing because you said himself. So it must be a female thing happening. More interest in the factors that contributed to when a horse enters the turning part of the track. More interested in the factors that contribute to when a horse enters the turning part of track. Let's check it out. So that would be more, what do you call it? I forget what terminology it is, but the force is going down on an angle. So there's got to be some horses. I know there's some horses that are way more faster than others around the track. A little bit of horse bedding. The barber doesn't exist. The barber doesn't exist. Really? Do you shave yourself? If not, please come in and I'll shave you. I shave anyone who does not shave himself and no one else. Who shaves the barber? Maybe the barber doesn't shave. Who says the barber shaves? The barber doesn't shave. And that's my final answer. But it's just a sign that says that, right? It's a paradox. Answering this question results in the contradiction. The barber cannot shave himself as he only shaves those who do not shave themselves. Ah, okay. Thus, if he shaves himself, he ceases to be the barber. Conversely, if the barber does not shave himself, then he fits into the group of people who would be shaved by the barber. And thus, as the barber, he must shave himself. Ah, sure. Okay. Or doesn't shave at all. If I was a barber, I don't think I'd shave. I'd grow a gigantic beard. Let me just finish this off. So you lay down the cars, make a horse track or whatever it is, and then take the aces. Right? So you can play with any number of people if you're, this is a family game. Right? So take the aces. If you're four people and each one is a different suit ace, and then you have the cards and you start flipping cards. Right? So if the two, if five of spades, I don't know how to draw spades. Here's spades. If the five of spades shows up, then the person with the spade moves five spots. So in general, you only really want to play with four people. Right? So one, two, three, four, five. So the spade goes to here. And then you flip again. And if, you know, three of diamonds shows up, the diamond goes three spots. You flip again. If a seven of spades shows up, then the spade goes up seven. Right? And that's the game. Very simple. Fun to play with family. Being female. Rottle. Rod. Red. Red. Oh, I'd like to choose an answer about barber being female. Never trust the bald barber. Sometimes they're the best. Sorry to interrupt about the barber. I thought you would find it interesting. Yeah, fun. Fun, Spider-Man. As far as the horse going around the track, I would assume the smaller horses would be at an advantage. Like for example, Arabian stallions, they're small, sleek, fast. Right? I have the simple equation. Anybody that comes up with a simple equation usually looks pretty difficult. My username, Frank. A to the power of N plus B to the power of N equals C to the power of N. How to prove that there are no positive integers for A, B and C that satisfy the equation for N greater than two. And that's the kicker. N has to be greater than two. Because if N is two, then we're into the Pythagorean theorem. If it's a triangle, right? A squared plus B squared equals C squared. I don't think that's a simple question. I'm pretty sure that's on somebody's website that gives you rewards for giving proofs of these things. Right? Mask of Raven would know this. Mask of Raven would know this. Everything about math, is very nice and topic. Yeah. Yeah. Just kidding. Funny. Funny. I swear, there's got to be so many people here, or not you guys, but on Twitch, that are taking high school mathematics and are struggling with high school mathematics, and they just don't know that they can get help. All right. Hilarious. Nuftir. I don't know what that is. Blam. By the way, gang, thank you for the follows. Thank you for the subs. If I've missed any subs and the follows for sure. I sort of read the chat, look at the math and look away and get distracted. So I had once an occasion which I stepped on. I had once an occasion which I stepped on like two numbers. These get natural numbers. I'm not sure what that means. Differentiation and integration walk into a bar. A fight ensues immediately. They both cancel each other out. Bamboo. Can you find a set of three different numbers for this? One of them would be two, right? Two plus two plus two equals two times two times two. I can find one set. What else? Zero. So there's three set, three, two numbers. So it would work for if they're all zero, if they're all two, one, two, three, one, two, three. And you could do it for one, two, three. One plus two plus three is six. One times two times three is six. Sure. We just did. Right? Oh, that's right. Two, two, two, six. So zero works. One, two, three works. All right. They shall be different. Others get periodical results when taking raising number like divided with a prime number. The end-grader and two-proof reference above. I'm pretty sure that's Fermat's last theorem. Good luck proving it. Yeah. I think we've had that question pop up before. That's why I recognized it. Right? The other question. A plus B plus C equals A times B times C. So zero works. So zero plus zero plus zero equals zero times zero times zero. One, two, three works. One times two times three. I said two, two, two, but two, two, two doesn't work. My mistake. So that's three, two we found. Read a book about Fermat. And there's an amazing documentary about Fermat's last theorem. It's really good. Oh, A, B, C do not equal each other. Oh, different numbers. I missed the different numbers. So zero, zero, zero doesn't work. So one, two, three works. Right? The other one, someone said zero, negative one and one. Yeah, zero, negative one and one. Cool. Zero minus one plus one is zero, zero times negative one times one is zero. What else? You know what? You could find an infinite number based on this. Could you? Yeah, you could find an infinite number based on this. Zero minus n plus n, because this would be negative n, plus negative n minus n equals zero times negative n times n. So there's your infinite set. Does zero over zero equal one because same number, no. Zero doesn't work that way. Chichou, do you have any studying tips on how to remember transformation rules better? No. JJ, the best way to remember that stuff is just to keep on doing, just to keep on doing. Right? You just have to practice. And for n greater than, oh, n greater than two. Missed that part as well. All right. Oh no, this wasn't for n greater than two. That was the Fermat's last theorem one. What is the smallest whole number that is equal to seven times the sum of its digits? Or n greater than zero. It seems you're getting you to do their math on work. If these are riddles math on work, you guys are going to fail. If you're trying to get Chichou to do your riddle math on work, I'm brutal at these types of riddles. I miss words and questions, right? Like I didn't register to me that the numbers have to be different, right? Andrew Wiles proved Fermat's last theorem about 20 years ago. It took him about 10 years of work. We can give it a try if it's going to be a long stream. I wrote stuff. And seriously, the documentary on Fermat's last theorem is amazing. One of my favorite math documentaries. Never mind. Wolfram Alpha can solve it for C. Wolfram Alpha is good. I use Wolfram Alpha somewhat for stuff. It's fun. It's a good website, actually. It's a very good website. You know what one thing I don't like about it is? It's not open source. And they put a copyright claim on stuff that you do or they used to anyway. So if you use their website to do data analysis and you use their methods in anything you publish, they put a copy. I think so, the technical stuff I read. Imagine you have nine balls. I wouldn't be able to walk. And one is a little heavier. Oh man, I'm in trouble. I gotta go to the doctor. Sorry, you have to say it. You have a beam scale and are allowed to weigh three times to find the heavier ball. Let's check this out. Let's read the other one, too. The two-digit AB. Oh, we've got a couple of riddles going on. Oh my God. I love Spider-Man. Math is fun. Math is fun. Hey, quick question. Serious medical aid, right there. Imagine you have nine balls and one is a little heavier. So you got nine balls. Let's do it. One, two, three, four, five, six, seven, eight, nine. All right. I love Spider-Man. We'll read your thing after this one. Can you explain all of calculus to me? Sure, calculus is an introduction of time into mathematics. So it's the rate of change. So going into calculus, if you're studying calculus, just think of it as time, rate of change. And the only absolute in life is change. So calculus is pretty damn important, right? A little heavier. You have a beam scale and are allowed to wait three times to find the heavier ball. What would you do? So we have a scale. We've got three, three times we could weigh things. What would you do? And we've got nine balls total. I mean, the ideal thing would be you would break it in. What would I do? I would do this. Let's see if this is going to work. I would weigh five balls in one, four balls in another, right? And you would calculate per unit ratio. So you would weigh this. You would put five balls here without work, and then divide whatever you get by five. Put four balls here. But three times doesn't work. And you get this number, right? If this is bigger than that, you know your big balls in here. And then what do you got to do? If you had, if you could do it four times, you could do this easy. Break this in half again, weigh them. And then, you know, you can do the next one and you're done, right? Like a seesaw. Moving around. Oh, like a seesaw. So it's like this. Oh, my bad. So that one we could do with four weigh-ins. Pretty sure. When does calculus turn to physics? Mathematics is just the language, base language of everything. It's a beam, beam scale. That's not what you call it. So we got this guy. So we got nine balls. So what are we going to do? Nine balls. So what would we do? Do we have to have all nine balls on the beam scale at the same time? You have a left and a right side of that scale. How is that scale? How is that? I don't know what it's called. I don't know what it's called. Just pit it. So you can't, you have to weigh all the balls at the same time. So you can't take eight balls and put them. Always count two of them. Just pit it up and weigh the heavier half each time. You're free to do what you want. You're free to do what you want. So I would put four balls here. Four balls here. Right? If this thing is level, whatever ball that was left out is your big ball. I'm just cracking up saying that. Twice you get the answer until you have the last. So you weigh it once. Four here, four here. I'm just exercising. I don't know if that's the answer. So if these are totally level, then that one is the ball you're looking for. If this tilts, then obviously the heavier one is going to be on the side where it's tilting down. So if this thing goes down this way, you eliminate these guys, then you put two here, oops, two here and two here. If this one tilts, then you put one here, one here, whichever one tilts is the big ball. Right? Twice you got the answer until you have the last two. Same solution, best case, check. Cool, cool. You can just add two balls evenly and when it tilts, you know that seems like cheating. That's true, Dante. You could do that too. Two balls here, two balls here. If it tilts, then one of them is to have your contains the heavier. So you could actually theoretically do it in two measurements. This one, if you're lucky, you could do it in one on the first go. You just put one ball on either side. If they weigh the same, you discard them. Repeat three. The kicker is. So one ball, once, twice. You could only do it three times. You could only weigh three times. Right? Because if it would be multiple measurements, so to speak. Okay, I got it wrong. You're allowed to weigh two times only now. Hey, you're changing the rules of the game. No, I mean, you could start with one each and keep adding, but that should count as multiple measurements. Yeah, that would count as multiple measurements. That's what I would think too, right? So if you added those guys, if it stays level, then you gotta add more. You add those ones, keep track of what you're adding. If it stays level, you gotta add more, but that's already passed the two measurements. Right? I swear, there's a similar problem of weighing 13 people with identifying one person being heavier. Yeah, I mean, to use two on one side and don't need four on start. So if you use two, if one is heavier, you got on the second one. If you use two, one is not heavier. How would you do it with two weights? I don't know how you would do it with two weights. Split the ball into three groups, Yucho. Three groups. Oh, split the ball into three groups. That's not a bad idea. Let's check it out. But then how do you isolate the one that's the heaviest one? Oh, because it's three. So split them into three, right? One, two, three. One, two, three. One, two, three. Take this one and that one, put them here. Right? If it stays level, then you know the heavy one is in this one. Right? If it tilts, discard this one, and then take two of these guys, put them here. The one that tilts is the heavy ball. If it stays level is this guy. Great. Break them into threes. Nice. Zoot. Awesome. Right? Oh, logic takes place. Yeah. Break them into threes. Awesome. That's better. With the other way, if you're lucky, you get it in one way. And victory, victory. Awesome. That was great. What was Spider-Man's little riddle? Spider-Man's real or Spider-Man's question. Let's check it out. I love Spider-Man. What have we got? Let's check it out. The two digit number AB stands for 10A plus B. Since the first digit represents tens, and the second represents units. I'm already confused. If 10A plus B equals 7A plus B, then 10A plus B equals 7A, 7B. And if 3A equals 6B or more simply A, that is, the second digit must be twice the first. The smallest such number is 21. I'm just going to write down the equations. That's what makes sense to me. 10A plus B, 10A plus B is equal to 7A plus B. You got that one. 3A. Actually, the other equation is A equals 2B. That's your first equation. That's your second equation. You got two equations, two unknowns. You can solve for this easy. I think so anyway. What are chicken dinner? Yeah. What are chicken dinner? All you would do for this is just substitute. Here, we already got this. A is equal to B. 2B is just something in there. But this is just going to be equal to zero. It should be. 10 times 2B plus B. I don't think this is a solving problem. This is just 3B times 7 is 21B. This is going to be 20, so 21B. So 21 equals 21B, so I guess the answer is 21. Is that what we're doing? Yeah. Substitution. I really love doing, just explaining to people, students anyway, to solve for one unknown, you need one equation. So solve for two unknowns, you need two equations. Three unknowns, three equations. Once that kicks in, if B does not equal one, but B was the units, I think. Something along that. 10A plus B, since the first digit represents 10s and the second represents Oh, units, you mean the first single digits. Cool. Cool. That sort of makes sense. Serious riddles. The answer must be 42. If B equals one, I misspelled. So what do you teach? I teach math. Math and physics. Lots of math. Not too much riddles. I'm not good at riddles. Amor, it's weird. I like problem solving, but riddles trip me up because of the wording, I think. How good are you at finite math, business math? Business math? We have a playlist, quantum paradoxes. Too funny. If you go to my YouTube channel, we have a section on personal finance. I have a personal finance playlist. I don't know if I'm good at business math. I just have experience and investing and playing the markets and understanding our economic political system. My own. I had long times on calculating at the station for nearly one hour several times. The answer is always 42. Hitchhiker's guide to the galaxy, super computer, the size of the planet I calculated for millions of years. I think he needs to upgrade. He needs to go up and order magnitude. I think Hitchhiker's guide to the galaxy, the next version, I think the answer will always be 420. What is the smallest number that increases by 12 when it is flipped and turned upside down? Flipped and turned upside down. Riddle, riddle. I tried raising four digit numbers divided by primes which result in the pre-order, pre-order result. Technical analysis. Technical, I used to do some, what do you call it, technicals on markets. Yeah, for sure. I was trading rudimentary stuff, simple stuff, but it's basically ratios and draw lines and break out, not break out, look at the short number, short squeeze, all that jazz. Barbara's job is to shave every man in town who doesn't shave himself. Wait a second. This was the same riddle as was posted earlier. My answer was the barber is not a man, not male. That's what I told peeps an hour ago too. Yeah, yeah. Lurker, I think Lurker, you're the one that brought out the same riddle, the same question, right? I may refer to that and that, which is 42 possibly trolling. What does determining why women don't like men mean? I don't know. Be nice to people. If you're nice to people, you'll come across people that don't like you, no matter how nice you are, but overall people will like you if you're nice to them. Want the answer? Sure. Spider-Man, what's the answer? 21. I thought we did that. No, wait a second. You posted another one. What is it? Oh yeah, yeah, the smallest one when you flip it. Sure. Spider-Man, what is it? Let me read it again. What is the smallest number that increased by 12 when it is flipped and turned upside down? What? What is the smallest number that increased by 12 when it is flipped and turned upside down? Mirror, mirror. Spider-Man, what's the answer? Very good. All right, Chicho. I'm going to head out and do some homework. I'll join back if you're still streaming when I finish. Yeah, we're going to be probably quitting in pretty soon. JJ, thank you for popping by. Hope you have a fantastic day and happy homeworking. Life advice with Chicho. The answer is 86. Ah, when it is turned upside down and flipped, it becomes 98, which is 12 more than 86. Cool. Cool. I got to remember these riddles and put them down, write them down somewhere. Maybe at some point when I'm doing a build, Hicks breaks, I re-wash these things and I'll make notes, take my own notes. Fun. Should we call the stream gang? Should we call the stream? We're almost coming up to two hours. And my voice is holding out, which is good. I'm fighting the flu, had the cough and stuff, so I wasn't putting multiple streams together, just doing two at a time. I feel lost and lost somehow sometimes. Me too. Everybody does. Man, everybody does. Look into a documentary called Forbidden Knowledge, I think it's called. It's about a mathematician making a documentary in honor of his three favorite mathematicians. And the documentary, that's my favorite document. Well, it's in my top five favorite documentaries or one of top 10 documentaries of all time. It's a documentary about his three most favorite mathematicians, and these are like huge mathematicians, Google and this and this and this. And all three of them went crazy trying to understand infinity. One of them killed himself, one of them went into an insane asylum, and the other one I think killed himself too or something like this. So I feel lost in math somehow sometimes. You're not alone. You're not alone. You actually have a seat with some of the greatest mathematicians in the world. No professional. I like fractals. Did some explaining and programming for it. Nice. A username, Frank. No links in chat, only on discord. Fractals are awesome. Fractals are beautiful. Okay gang, let's call the stream. Let's call the stream. Thank you for being here. Thank you for all the questions. Thank you for the rules. Thank you for the answers. Thank you for the collaboration. We solved a really hard one. That was super cool. I wish you a very good night. You as well. You as well. I hope you guys have a fantastic evening, fantastic day, fantastic morning, right? And if you can make it tomorrow night, 8 30 p.m. Pacific time, my time, we're going to do a math stream regarding the coronavirus. Specifically, we're going to start off by looking at the numbers and looking at some charts and graphs just to reduce the hysteria on the world, but really look at the numbers to see what we know so far from what's been released to get an idea of what's happening, right? And then we'll see where the conversation takes us, okay? Good stream, teacher. Full of balls and barbers, base riddles. I'm going to call it a night. Hope the flu gets better, man. Me too. It's lasting forever. Never had it last this long. But it's good. I'm functioning at around 70-75% improving. That's just good. Which is good. Okay. Take care, everyone. I hope you guys have a fantastic, fantastic day, and I'll see you guys tomorrow if you can make it. Bye for now.
