  • thankyou very much for giving me this chance to do well in maths :)

  • @AstralXRomance1 binladen hahahah the big lie for u .. so ur country can drill oil from the middle east oooh noo we fighting terrorism ....show me one proof that binladen was killed as they say. picture (not photoshoped ) video! burial no one saw nothing it was a an episode of america got fakes..he is dead years ago keep paying ur taxs to ur government ..they kill people for u i hope u happy

  • @boody19 Oh: I am. Heil obama!

  • @boody19 ... hey i am too . and proud to be..

  • Thumbs up if this taught you Binary lol

  • It's interesting but using a multiplication table and using the usual method is much faster, specially for numbers with more than 2 digits.

  • @tiagotrinidad What about this one for multiplication? "Speed maths- Multiplying without multiplying". Click on my username and check the vid. Cheers.

  • awesome!!!!!!!

  • @B7acKLioN Arabs have nothing to do with ancient Egypt. They invaded in 640AD look it up.

    Also look up the difference between upper and lower Egypt.

  • @boody19 What kind of Egyptians are you talking about. Before and during the Greek time period or after the 640AD period when the Asiatics invaded that land because the Greeks talk about the people of that land and they certainly look nothing like the people that's living there today.

    Question how many Arab tribe have a cow as a GOD and is treated as such?

  • @OriginalBloodKin none arab tribe over the dawn of time worshiped a cow ! man get ur info right stop watching western media

    so british now are no British, Americans are invaders ...etc

  • egyptian MATH. -.-

  • @B7acKLioN  hahah what r u talkin about nigga u were brought salves cheap slave flunk hahahah

  • tHIS HAS REALLY HELPED ME WITH MY MATHS

  • Comment removed

  • @boody19 what do you mean by next iran???

  • @xAngeloftheDevilx nothing bad about Iranians i mean the governmental system

  • @xAngeloftheDevilx i mean the media propaganda .like evil country nukes...etc killing women bla bla bla watch?v=hyZr1-jNkL0&feature=g-­all 

  • @boody19

    uuuuh why did you send me that video, i'm chinese

  • @xAngeloftheDevilx the ancient Chinese used the same method: the hexagrams of the i ching work in the same way... although not sure if that's why broody sent it to you

  • @mothnrust

    no, lol that's not what i meant, he just randomley sent me a video about to arab guys talking about Iran. :)

  • Oh and the division did not work for 24/6. It said it was 2?

  • This is great! But I had a problem that I fixed. Okay, so 12 X 124 (12 - 1,2,4,8,16, circle 4,8)(124 - 248,496,992,1984, circle 992,1984) 992 + 1984 = 2976 (Which is not the answer) Then I Divided it by 2 (Split it in half) which = 1488 Which is the answer. Hope this helped anyone? So you have to divide some of them, and not others. How can you tell which one needs to be divided and which one doesn't?

  • @boody19 getting rid of the damn religion once and for all would limit wars to greed... Not better, no, but less reason to kill your neigbors and less ignorance all together thus more easy to react to greedy capitalist ...see where i'm going with this ? ...

  • @theREALmegaverse who killed his neighbors man if u r talkin about sinai and egyptian israeli war read history we killed no one we started no war ...israel just appeard in like 1950 out of nowhere and started to invade every arab land they got palastine..egypt..syria jordan Lebanon these countries were completely stable ...israel is they only country that have nukes in the middle-east all the conflicts were to regain land .. media is fake controlled fake fake

  • 5 x 13!

  • Could they teach this in US schools? I wish they would've in my classes.

  • @mothnrust sure my friend will happen in the near future inshallah . u have to know that this generation of egypt were born and rasid with the scenes of palatine pain that deeply affected our hearts .... future shall witness u r our brothers and sisters

  • we know that and we won't let that happen ...we just love our land our army is strong yeah but will not attack country only if they try it first. we love u all

  • American schools fucked up bad.

    We could have been smarter, doing magic and shit, because of math skills

  • how do you get the square root of pi with egyptian math ?

    hehe

  • Thanks so much!

  • Why the FUCK wasn't I aware of this in primary school?!

  • I would a love to learn this when i was in school.

  • This Is FANTASTIC! Thank You.

  • So true but they forgot to mention that they learned it from the ancient Ethiopians.

  • how do you do the division thing if the numbers are uneven

  • @sharpezor do you mean if the number doesn't divide exactly? say 1076/25? then their would be a remainder of 1, that is 1/25, or .04

    there's some more complex examples in pt. 2 but it's a bit tedious and there are also a couple af flaws in it.

  • @mothnrust Thank you for taking the time to answer.

  • This method is different from what we do in the sense that in this method we arrive at the answer by stacking together parts of the answer until our column reaches the exact height of the original problem. We take the biggest brick we can fit put the next biggest brick on top that will not make the total go over the number being multiplied. so 43 = 32 + 8 + 2 + 1. We skipped 16 and 4, because those would have taken us over 43.

  • Thats nice, but you can't do 999:6?

    Any id what to do?

  • It's easy. This method works if the answer is an even number. 2 to the 0 power gives you 1 (the starting number for your table), but to go beyond a whole number answer you would have to go into negative powers, aka 2^-1, 2^-2, 2^-3. Your table would basically start with some number lower than 1, and you would keep going until you get an answer. Instead of just 1, 2, 4,8, you would have something like .125, .25, .5, 1, 2, 4, 8

  • @ElCidX they probable only looked for whole numbers and not anything else.

  • WHOA. My mind = blown x__x

  • im jus sayin wicked cause thats hwat we excatly did in electronics engineering :: like the way of explaining

  • :O i can't believe i actually enjoyed a math vid!

  • Well, they may not be teaching this in school, but my children are about to learn this!

  • This guy just blew my mind.

  • SO. COOL.

  • This is Ethiopian not Egyptian .

  • Cool Video.. I didn't know Peter Gallagher had a math whiz brother.

  • how would you find the product of 15 and 22? i tried to write it out and i wound up at a dead end. i punched it into the calculator and it showed 330 but the way you explained it was i would have to add the units that equaled up to 15,which was 1, 2, 4, 8 added = 15.wouldnt that mean that i would have to add 22+44+88+176+352?that cant be right.maybe there is a rule you did not mention in the scenario of more than two units to equal the lower multiple? like i would have to subtract unit 1 from 8?

  • @amira1295 You are correct, 15 breaks down into 1+2+4+8. So, the corresponding doublings of 22 are 22, 44, 88, 176 (not 352). Adding those together, you get 330, the correct answer.

  • @NWUCatsFan oh, yes. i made a mistake. thank you :)

  • Who invited the Jew? (I'm a Jew.)

  • I understood the math, but I could understand his choice of shirt...

  • Are computers based on this system, or did they just come across this method independently?

  • Hello from Reddit

  • If you do division of a non whole number you would use ... .125, .25, .5, 1, 2, 4,8 ... correct?

  • This is so hot. Absolutely awesome. ~ I laid in bed last night watching this & the other one and was just boggled. Great videos... off to go share w/ my friends. =^_^=

  • This is cool. Reminds me of some Indian maths, Vedic or something... it's not talking about the same thing, but it shows how ancient civilizations have some amazing knowledge that we would benefit from being taught at schools.

  • I really want to watch this but the scratching sound of marker on paper is making me lose my mind!!

  • To me, base 2 makes MUCH more intuitive sense than base 10.

    /epiphany

  • As explained in the beginning, there's base 10 values of (100-10-1) and when you go to base 2 it changes to (16-8-4-2-1). I would assume this works with any base, but I'm uncertain how that would work; for example base 5. Since they both start with 1 and the second value is usually the base you're working with (base 10 would start with units of one, then the "10's" value followed by hundreds), I would assume base 5 would be something like (?-?-5-1).

    This is odd to me. Unsure how to work it out.

  • @PFC33 it would go 1 -5 - 25 but i doubt it is useful for anything. the beauty of this system is its simplicity, efficiency and logic.

    personally i think it is a tragedy it is not taught in schools

  • Oh, that's right. The exponential growth factor was what I wasn't taking into account.

    I agree, this is a rather interesting tool. I never was as interested in math until I saw this on the dailywhat and then looked for it on youtube.

    Just solved that problem I made up converting 49 to base 5. I didn't understand how that would work after working on base 2, but I realize that you can have more than 1 of the values for a specified outcome which gets the desired result (in this case, 144).

    Thanks!

  • Lol.. Now I made 2+2=10

    (Base 4)

    It's like dividing by 0, but it's doable apparently. :P

  • @mothnrust I think saying base 5 isn't useful for anything is unfair. There is nothing inherently nicer about base 10 than base 5, but we use base 10 in every day life. I can't recall the specifics but there are some calculations that are most efficient in base 3 (which happens to be the perfect mix between not too many digits and not too large a base for some particular calculation). There could easily be situations where working in base 5 has some advantage over other bases.

  • @mothnrust 5 +5 does not = 25 dumb dumb. your now squaring it. your doubleing it. or what the any base would be if you squared it. 1 - 1 - 1 - 1. you cant do 1*1=2

  • @mothnrust Actually, multiplying with 5 is just writing a zero at the end, and halving that. :)

  • @PFC33 As you move to the "left" in a number, you are out of values possible using only the previous digits. So, for "standard" counting (base 10), rightmost number is 0-9. Then is 10, then numbers up to 99, then 100. For binary (base 2), you have 0, 1, then 10, which is 2 in base 10, then 11 (3), then 100 (4). For base 5, you would have 0-4, then 10 (5) to 44 (24 = 5*4+4), then 100 which is 25. Said another way, the right-most digit is base ^ 0, then moving left base ^ 1, base ^ 2, etc.

  • There was no zero invented during the ancient egyptian times. So how did schneider come up with solution and attribute it to the ancients. zero came in third century from india and used by middle easterners.

  • @PFC33 There was no zero invented during the ancient egyptian times. So how did schneider come up with solution and attribute it to the ancients. zero came in third century from india and used by middle easterners.

  • @nyork321 Well, the Romans didn't have zero either, but they got around fine using Roman numerals that utilized the power of ten, or "X". The Roman ten did not require a zero numeral, since it was represented by a symbol. And I'm just using the Romans as an example; many ancient cultures did not have the zero numeral, since many ancient mathematicians found the concept of using nothing as a value to be absurd.

  • @PFC33 the only problem is that with powers of 5 you cant make all the numbers

  • great stuff! thanks for uploading

  • how about 1083 / 23

  • @Mandrake1942 sorry man you'll have to work it out for yourself, i can't get into individual calculations. you could look thru the comments as there are some examples and you could also watch pt. 2, although there are a couple of flaws in it and it's a bit tedious/nit picky (but hey, that's me :) )

  • @Mandrake1942 Well you obviously don't get a whole number since it doesn't divide cleanly. But you do get the same result as you would with traditional long division, which is 47 (remainder = 2). This would lead you down a couple of different paths depending on what you wanted the number for. Either do 108300/2300 to get more precise, or change the starting numbers to 1081/23.

  • This is amazing. they should definitely teach this school, so much simpler.

  • Comment removed

  • Call It. Friendo.

  • brilliant... i was always crap at maths... now i'm awesome!

  • And why have I not been taught this in school?

  • This is REALLY cool, and new to me. But we tried it out at home and of course the first problem we came up with was far more difficult to solve this way than our modern tradition of long division. Try 2000/8. That means you have to do your binary to ... I don't know...128? When we started adding up the doubles of 8 (612 + 256 +128+....you got a lot of options here). We decided it was tougher to come up with the even 2000 out of that set of characters than it was to just divide.

  • @SwimFlySwim 512, not 612 is double 256. i don't think it's more difficult, you just have to get used to it (although it's just my opinion).

  • The knowledge dropped broke my toe.

  • still don't understand how computers or egyptians compute decimals

  • I LOVE YOU!!!

  • your next clip should explain life's other great math mystery....."The Cell Phone Bill"

  • 1075 divided by 25 looks good and simple. but what about 1076 / 25 ??

  • @golafs well, in the example you offer, there would be a remainder of one, 1/25 (or .04)

  • @mothnrust yea, but how would the method that he uses work (i.e. the lining up of the numbers) with decimals. Where would the 1/25 go and line up with what?

  • @eitanwp not really sure what you mean. the fraction would go after the whole number: 43 1/25. am i missing your point?

  • Cool. That was awesome.

  • do girls get wet hearing this?

  • @thenfm im a girl and i can confirm this.

  • @UerMom i only want you confirming this if you're not a fat disgusting bitch eating a pint of ice cream. you have to meet the weight requirements first.

  • @thenfm Looks like she was dude

  • @thenfm why yes.

  • awesome

  • Why is the villain from 'no country for old men' teaching me ancient maths?

  • I don't think that guy knows any powers of 2 higher then 16... just saying.

  • @duododecahedron

    I don't think the word "then" means what you think it means.

  • I loved the explanation, but that felt tip pen kills my ears

  • i beg to differ The ancient Kemetic people were the orginally developed the Binary System, astrology, physics, psychology, medicine, engineering, and then spread and twisted to accomodate the rest of the world. Know thyself!

  • that is very fascinating. 

  • @roseasylum, would you say that the first humans were from india too...see that's the problem with this world every race/ethnic group wants to claim something to be their own and discredit the other.. and it's only the good things i might add, no one is rushing to claim the bad.. but @mothnrust- he said it best they looked to the universe and saw that everything came to be through a binary process! so anyone who took the time to think and give credit to a higher force-could have done it!

  • great presentation

  • Thanks so much for providing this video. This guy is great! and this system is so simple. It really rocks! We need to teach it to children, and throw away those darn times tables. Yech! ;)

    ♥ ☼ ♥

  • 1.take a deep breath

    2. think of someone u like

    3. press F10 5 times

    4. send this to 5 youtube videos

    5. look at ur backround

  • Per the division problem:

    But, if I have an even number as the dividend and my divisor on the right is odd or wont evenly form the number, then what? I will try a few practice problems and see how it works.

  • Awesome! that was sooo interesting! I've been busy practicing this method for like 2 hours now. ^^

  • can we make (102) square 2 whit this methode

  • of course!

    binairy number would be: 1100110 for 102

    corresponding next to those are 204, 408, 3264 and 6528. Add those and you get 10404

  • i have a question, im in the 6th grade and i asked my teacher what binary means, and i really dont know if she ignored me, or didnt hear me but what does it mean....

    also i didnt get the part totally where how you find out the product of 7 and 25.

  • binary is base 2. basically it's 0s and 1s (how computers calculate) but doubling as they go 1, 2, 4, 8, 16...

  • @mothnrust Is binary system from Egypt? Or are you trying to proclaim that Binary System was invented in Egypt? I am a mathematics student and the binary system that is used in computers today was first developed by India and then was spread to rest of the world world following Arabic country.. It is always good to take pride in achievements of your motherland but it is not right to twist the facts and represent it in misleading way.. I hope you will take this in positive way,,

  • @roseasylum, i'm not claiming anything, i just posted the clip because i thought it was a pretty interesting bit of history, and a good explanation of binary. i don't think the point is about who first used binary, but that they did use binary: as did the ancient Chinese. did it spead from one culture to another or develop independently? My feeling is, history is too obcured to know for certain.

  • @roseasylum This is the Dogon tribe mathematics before Egypt was name Egypt and before India learn this math from the Dogon tribe. The Dogan where the Kemet and kemet is modern day black Egyption of today. The Dogon tribe also discover the Sirius stars 1000 years before the telescope ever develop. check the Ethiopian math and the Dogon tribe math.

  • @roseasylum i beg to differ The ancient Kemetic people were the orginally developed the Binary System, astrology, physics, psychology, medicine, engineering, and then spread and twisted to accomodate the rest of the world. Know thyself!

  • @roseasylum ... Binary is a base for numbers (it represents base 2). Nobody "invented" it. It's simply another way to track numbers. You can represent any number in any base, but the reason we chose base 10 is because we have 10 digits on our hands, which make counting more simple for younger people. The Egyptians instead decided on base 2 (for whatever reason, perhaps a step up from the tally mark, as it makes mathematics twice as easy). They chose it, but did not invent it.

  • @tnbeastro77

    Binary means ALL numbers are represented using only zero and 1. It is needed in computers world since the computers use electricity, and electricity is only on and off.

    So, number one is represented as 1. Number 2 is represented as 01, number 3 as 11, number 4 as 001 and so on. Watch the video again and you will understand better the second time around.

  • Comment removed

  • @gigiontube You've got your examples wrong.

    (decimal) 2 = 10 (binary) (1 * 2 + 0)

    (decimal) 3 = 11 (binary) (1 * 2 + 1 * 1)

    (decimal) 4 = 100 (binary) (1 * 4 + 0 + 0)

    It looks as though you've placed your digits in the wrong order (in ascending powers of 2).

  • @T1MHughes

    LOL. You are right.

    My logic was perfect but my fingers were typing backwards as you see. I'm wondering how that happened. Probably I was really, really tired.

    Believe me, I know the binary and oct and hex etc...Still can't believe I typed everything in reverse. Oh, well.....

  • @tnbeastro77 when you count, you have to decide when to use another digit. because people tend to count on their fingers, people decided to switch when they count to 10. So they go, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

    Because of how computers work(they dont have fingers) they like counting only to 2. Also, they start counting from 0, so they say 0, 1, 10, 11, 100, 101, 110, 111, and so on...

  • what do you do if when dividing, the numbers dont go into each other evenly? (like 275 / 2) ?

  • you have a remainder of 1 - 1/2, or .5

  • 275/2

    We get to 137, rem 1.

    So, what do we do?

    Multiply the remainder with your base, for normal numbers this is ten. So you have 10* 1 = 10.

    Divide this by your divisor. This is your first decimal.

    10/2 = 5, rem 0.

    Final answer = 137,5.

    Off course, you can do it with larger numbers. Sticking with base ten you could also multiply with 100, and do two decimals at a time, or 1000 and do three and so on. 10^n where n is your amount of decimals.

  • w o oo oooo oooooooo h hh hhhh ! !!

    time to whip out a notebook,

    veda sutras math tricks are complex,

    THANKS! !! !!!!

  • that's interesting

  • Molto, molto interessante.

    Grazie!

    5*

  • well nice video but 0.0909090909 times 11 actually equals 1.

  • it only equals 1 through rounding. 0.09090909r x 11 = O.99999999r

  • Well, I'm sorry, but in fact 0.9999r equals exactly 1.

    "In mathematics, the repeating decimal 0.999... [...]denotes a real number equal to one."

    Quoted from wikipedia article "0.9999".

    Very interesting.

  • well perhaps we're splitting hairs but i think the key word there is 'denotes' , because technically it still has to be rounded up.

  • Sure, you're allright. Just wanted to share some cool informations not everybody knows.

  • yeah, that's cool - it's great to have the debate and find people interested in maths - to too many it's just buttons on a calculator

  • great video! i am still a bit confused on the decimal situation as well. like the instance of 23/11. Can you post another video explaining it? i get the subtracting part but if a computer doesnt use a multiplication table and you end up with a remainder of 1/11 that is where i get lost on how it computes.

    thanks.

  • part of the problem is that these days, since electronic calculators, people mostly think in decimals, rather than fractions, so people think of .09090909r rather than 1/11, which to my mind is not necessarily a good thing (although that might be because i'm from a different generation) and certainly not as accurate (because if you add eleven of the decimals you won't return to one.

    haven't really got the facilities or time to do a video but i will think about it, although not promising.

  • this was great it reminds me of bouline and.

  • my brain hurts.... learn math and other languages as young as possible kids... oh yea, and don't do drugs...

  • xD but mine hurts too and im only 20 and never done drugs T_T xD

  • what an awesome post...im def teaching this to my children

  • How would this be "explained" or be written if the numbers divided would not be a part of N (meaning without decimals)?

    Would it go the opposite way like:

    2^(-1)

    2^(-2)

    ...

    2^(-n)

  • sorry man, i don't understand what you're saying - you sure you're not over complicating things?

  • Well I'm thinking like if you divide 23/11, the answer would be 2,09090909090909... How is that number explained with binary counting?

  • 1 x11 = 11

    2 x 11= 22

    leaving a remainder of 1, 1/11, or .0909....

    does that explain it?

  • Partly, the 1 * 11 and 2 * 11 part but how would the leftover of 1/11:th be described binarily?

  • well Aron, you've got my head working on this one...

    i think the best way to look at it is to actually convert the numbers to binary - so, 23 = 10111 and 11 = 1011. now if we subtract 1011 from 10111 it leaves us with 1100 (12) now we repeat the process, subtracting 1011 from 1100, leaving us with a remainder of 1, 1/11, or .0909... - does that work for you, or am i just complicating things?

    thanks for your interest,

    jack

  • to add, 1/11 in binary would be 1/1011

    j

  • so then how do you differentiate between the instance of a 10 and a separate 1, 0.

  • sorry, i don't really understand what you mean. can you give an example?

  • i just got thrown off as to how the 1's and 0's of binary were corresponding to the Egyptian math.

    i was reading it as 10001 = 425

    as opposed to 00110100 00110010 00110101

    i didnt know that the 1's represented place values.....sorry im a bit slow lol

  • wtf why didint i learn this in school?

    i just wasted my whole childhood on bullshit

  • hahaha.I thought this was a joke.

  • really good explanation

  • Well it's very true.

    The power of 2 can represent in value of digits. It's just represented in another format.

    So every mathamatyical system can hold the same amount of digits. Us programmers learn that when studying Asembly.

    My name in Binary is 011000110110100001110010011010­0101110011 Then it comes to the characters ''CHRIS'' based on the Ascii chart. It's only a matter of conversion to one level to another. So all Numberic digits could be represented in any form

  • i like the Vedic way better...

    but this is very similiar

  • narf

  • What about floating point? Nice trick..all basic operations are addition.

  • The Egyptians definitely had "secret knowledge". I can't believe it took us 5000+ years to come up with the concept of Binary lol

  • @WaitingforChrist we didn't really need it until we came up with computing

  • the egyptians rocked ..

  • It is a good procedure you are just factoring thing before you multiply

    so how do you get the series 1,2,4,8,16,32?

    oh we multiply

    and the series 25,50,100,200,400

    oh we multiply

    and that bit he says about computers not using "memorized"

    multiplication tables, they certainly do, just not the same ones we memorize.

  • I agree with this guy, and have to add that he gave just two simple pre planned examples, you can't do it this way for every large number.

    and I don't think the computer use the way he told to multiply and divide numbers. cause there is also binary way of division
