 Hi, I'm back just for a quick a quick little video. I wanted to talk about something that I think will help everyone Understand the or sort of get the most a canada from the videos I've already put online and Hopefully it'll set everyone up for the next set of videos that are coming up. It's specifically related to a question I got Sent to me a few months ago that I haven't had a chance to answer yet because well I had a lot of things on my plate and I had never been asked this question before So I really have to think about it to come up with an appropriate answer Now I've done a little write-up on my site and I'm gonna have that available On Chicho TV probably in the miscellaneous section or something like this or questions, maybe So there is a writer up there and this video is gonna be embedded in that write-up So hopefully the double dose of written explanation in the video Will clear things up. Okay, the email that I got was It basically the main the main question was why is a negative and a negative equal a positive Now there was a few other questions in the email as well But all of them were dependent on this one question being answered or this one One problem that this person was having now I did a little bit of research online And I found out that there's a lot of a Lot of people have asked this question and I found some answers, but a lot of the answers were Based on proving that a negative and negative equal the positive in math What I want to talk about is why this property exists why this is true now the best way the simplest way to think about this is Just like the English language where a double negative is a positive Mathematics were the same way and negative and a negative makes a positive So it's both languages are consistent with each other now in the email the person Wanted me to give an example where you know two negatives make a positive one of the problems that that One of the issues with this question was that it was assumed that a negative number had a negative connotation that that that was You know, it was a bad thing So, you know in the email the and online a lot of people were asking that you know They don't know any examples in nature where two negatives make a positive now You can't think that way when it comes to mathematics math is is a non It doesn't have any emotions attached to it. It's just a language. So when we say We have a negative number It doesn't mean it's a bad number or if a positive number is a good number and negative number It just means it's a negative number the negative part is is a property of that number It's like having black hair or white hair or yellow hair or blue eyes or you know two arms one arm It doesn't make a difference. It's just a property. It's a trait of a number. Okay, so a negative number Doesn't have any emotions attached to it where two wrongs make a right. It doesn't work that way You know in in life It really doesn't work that way two wrongs do not make a make a right but in math when two properties of One kind Merge they might come up with a different property which could be two negatives and when they merge They come up with a positive now the best example that I could come up with and I thought about a Lot of them But this is the best way that I could explain it as an example goes is let's assume a single person is Is Given the property of a negative number and let's call it a negative one So a single person is negative one, okay? Let's call a couple a Married couple or just a couple doesn't you don't have to marry to be a couple. So let's just call a couple positive one, okay, so Given this Let statement and in mathematics you do a lot of let statements where you say let x equal something So you're defining what x is Right now. We're doing the same thing We're doing a let statement and saying a single person is negative one and a couple is a positive one They're one couple. Okay, so if we take two single people negative one and Merge them negative one times negative one you get positive one which is consistent with our Let statement which is consistent with the language of mathematics and it's also consistent with English now keep in mind that in math words have meaning so and In mathematics means multiplication with In mathematics in general means Edition, okay, I'm not sure if you can see this actually with maybe I should make them bigger Let's say and Equals multiplication and width is equal to addition. So right now We sort of prove to ourselves that two single people merging and Negative and a negative is equal to a positive if we use the width statement. This also is You know consistent it's true. So we could say let's say two single people go to a party. So One single person Comes with another single person to a party. Then you have two single people. Oops. They should be a plus, sorry so For both operations and multiplication and addition. They're operations. Okay, this dot really means multiplication So with both operations the and statement and the with statement a single and a single makes a couple a Single with a single makes two singles. Okay and That's basically that's basically what a language is we create symbols to Explain certain properties that we observe and We take those properties merge them together. We do operations such as and with division whatever you want to come up with Something new and then with that something new we can take it and Merge it with something else and create something else. Okay, so it just continuously grows so once we understand how to use a language it allows us to You know just learn more and more because everything we everything that we learn everything that we come up with new things that we come Up with we can take them and expand on them and combine it with something else and see what happens Okay, so keep that in mind and negative number Doesn't have negative connotation. It doesn't mean it's bad or it's good It's just a property of that number. It's just a language. Okay these are just symbols that we use to Convey information to talk about things that we think we know now sometimes we're wrong, but This is what we this is the best we're able to do right now math is The best language that we have been able to come up with to be able to explain the world around us now in the future a New language may come along which makes math You know a subset of that other language where that other language encompasses a lot more concepts Than what math can do right now and that is something that you know scientists are looking at You know that there's different branches of mathematics where they're trying to go into new areas and try to come up with You know a certain way to solve problems which can't be solved with mathematics or there is no proofs for a mathematics So there's got to be new Sort of a new thought pattern coming along But before we can actually come up with a new language or one of the best ways to come up with a new language is You know learning the languages we already know that way We're we can avoid any pitfalls that we've had with the other other languages So keep that in mind math is not the ultimate language. However, it's the best language that we have so the best thing we can do is understand all those properties and That's the only way we can come up with a new language or a new thought pattern where we can explain more and you know Try to understand more about the world. We live it I hope this helps the write-up is on chicho and You know this video explains Exactly the same thing that I talked about in the write-up. So if you feel like I read that or just watch the video It should be fine. I hope that helps and I'll see you guys. I guess Towards the end of August I'll try to refrain from making any more videos because I really want to do it in one shot and get rid of all the other Projects I'm already involved in okay. I guess we'll talk later. Okay. Have fun
