Why can't you divide by zero? - TED-Ed 

0 Divided by 0 = 0

In my mind, I say division is giving a fixed number of ice-cream to a fixed number of kids. If I have 10 ice-creams, and 5 kids I can give them to, how many ice-creams does one kid get? The answer is 10/5=2. However, if I have 10 ice-creams, but there aren't any kids that I can give them to, how many does one kid get? Well, we can't say zero OR 10, which means such an operation is undefined.

What about Lelouch? He got divided by Zero lol

If you divide by 0 it is 0 because say you have 10 cookies if you divided them between 2 people each person gets 5 well we all know that but if you have those 10 cookies to 0 people how many dose each person get well if you have no people to give them to then no one can take them there for each person gets 0 because know people can take them

try: # Stay safe during the Coronavirus! 10/0 except: if ZeroDivisionError: print('Answer is INFINITY STONE!')

True

Yup

The most true thing I’ve heard in a long time

It is not like that. I think he is trying to say something about the function that is how a 1/x function behaves when x tends to zero.

Well 0="0" 0=[] But "0" is not equal to []

@@tiredHooman I smell JavaScript here :D

"1=2" = 0

@@tiredHooman thats due to implicit conversions. 0="0" assumes you accidental used "0" as CHAR. 0=[] assumes that a number 0 is the same as a NULL "0"=[] doesnt work because a CHAR is a string of length 1 even regardless of what is in it and 1 does not equal 0 this of it like this "0" = [] is the same as asking "0000000000000000000" = [] both are false

In a sense that is a perfectly valid result. Do mathematicians not know how to use it (I suppose: "yet")? I'm sure they will find a big use for it if not already.

Which also means that it can’t be a function, because that would leave two outputs for the same x value

Yes. And if you try to find a solution to y = 8x +1 16x - 2y = -2 And do the math: 16x + -2(8x + 1) = -2 16x + -16x + -2 = -2 0x = -2 - -2 0x = -2 + 2 0x = 0 0x/0 = 0/0 It comes out to: 0/0 = ∞ So the solution is infinitely many. Which, in my logic, proves n/0 = ±∞ Depending if n is -i or i where i is an rational or irrational number.

@@hstochla it can also be a solution of two linear functions. Where there's the same slope and y-intercept. y = -x 7x + 7y = 0 Equations ↑ Steps↓ 7x + 7(-x) = 0 7x - 7x = 0 0x = 0 0x/0 = 0/0 Solution ↓ 0/0 = ∞ There are infinitely many solutions to this problem.

imo i don’t think this is the best way of looking at it as 1/x^2 goes to positive infinity from both the right and left, but you still can’t divide by 0

so it’s ♾️

10 ÷ 0= 0

No, that one discovered space.

Before that, there was already "i"'s all over America, but they didn't count since they were technically imaginary.

I made new rules check this out lol... The recent discovery of net energy gain produced in a fusion reaction made me realize I discovered the formula for cold fusion a while ago. Here is the equation... 0^a * 0^b = a * b This means... 0^1 * 0^1 = 1 * 1 Which means... 0 * 0 = 1 * 1 Which also means ... 0 * 0 = 1 I'm attempting to highlight there is a spectrum to what we call nothing or what we mathematically denote to be 0. Conceptually speaking, what we call/describe as nothing physically holds energy and this is proven by zero field energy or the fact that absolute zero still has yet to be discovered to naturally exist in this universe. This math is a product of my attempt to mathematically describe the energy stored in vacuums of space we tend to call nothing. Here is the math/formula that lead to this conclusion... x/0 = 0^x If you solve for x then... x = 0^x * 0 If x = 1 then that means... 1 = 0^1 * 0 Which also means... 1 = 0^1 * 0^1 Because I'm still a mathematician, i will still acknowledge and say... 1*1 = 1 So due to the transitive property and continuing with the equation above, this must be true... 1*1 = 0^1 * 0^1 Which lead me to the conclusion... a * b = 0^a * 0^b Or... 0^a * 0^b = a * b ( You should be aware I've taken Algebra 1 and 2 and AB Calculus and I'm still saying what I'm saying.

​@@tonysparks1682 > x/0 = 0^x This is wrong and any steps that involved it as a hypothesis are unsound. 0^a * 0^b = a * b This is nonsensical. 0^a = 0 * 0 * ... [a times] ... 0 = 0. Your formula holds if and only if a * b = 0, and your second step - assuming a = b = 1 - is thus unsound. I don't know what algebra courses you've taken, but if they did not make the fact that this is completely incorrect mathematics clear, they weren't very good.

Since the time of the ancient Greeks, the philosophical nature of infinity was the subject of many discussions among philosophers. In the 17th century, with the introduction of the infinity symbol[1] and the infinitesimal calculus, mathematicians began to work with infinite series and what some mathematicians (including l'Hôpital and Bernoulli)[2] regarded as infinitely small quantities, but infinity continued to be associated with endless processes.[3] As mathematicians struggled with the foundation of calculus, it remained unclear whether infinity could be considered as a number or magnitude and, if so, how this could be done.[1] At the end of the 19th century, Georg Cantor enlarged the mathematical study of infinity by studying infinite sets and infinite numbers, showing that they can be of various sizes.[1][4] For example, if a line is viewed as the set of all of its points, their infinite number (i.e., the cardinality of the line) is larger than the number of integers.[5] In this usage, infinity is a mathematical concept, and infinite mathematical objects can be studied, manipulated, and used just like any other mathematical object. The mathematical concept of infinity refines and extends the old philosophical concept, in particular by introducing infinitely many different sizes of infinite sets. Among the axioms of Zermelo-Fraenkel set theory, on which most of modern mathematics can be developed, is the axiom of infinity, which guarantees the existence of infinite sets.[1] The mathematical concept of infinity and the manipulation of infinite sets are used everywhere in mathematics, even in areas such as combinatorics that may seem to have nothing to do with them. For example, Wiles's proof of Fermat's Last Theorem implicitly relies on the existence of very large infinite sets[6] for solving a long-standing problem that is stated in terms of elementary arithmetic. Yes, I copied that off of Wikipedia

Is math artificial, or part of nature?

Physically possible is pretty irrelevant to math, though. That's something for physicists and engineers to worry about. You can define a math where dividing through 0 is possible. You're probably going to have to give up some other features the more common ones have, like the distributive property or multiplicative inverses, and it might not be terribly intuitive. But it is hardly impossible. Dividing by 0 isn't forbidden, it's just not defined in the default math most people learn.

@@Llortnerof R/iamverysmart? Okay, but physicists and engineers _literally use math._ The reason math exists as it does is because of the world we live in. Universal constants in physics and astronomy were designed to allow us to mathematically calculate things we can't or don't have time or resources to study. And the results contribute to real-world projects. How do engineers build structures that can withstand hurricane force wind? Well, they have to calculate certain numbers and dimensions... with math. Force, vector, friction -- they're all real concepts translated into mathematical form in order to quantify them. Math does hold true because we made it that way. Sure, we could make it _not_ that way, but that wouldn't make much sense, literally or figuratively. So I really don't get the point of calling out my post by saying it's only one kind of math. Math is math. There's only one. If you wanted to "define a math" where other things are possible, that would mean changing math. Sure, you could say dividing by zero is possible, but when an apple falls from a tree, you wouldn't be able to calculate how long it takes to reach the ground. Also, when I say "physically possible," that's not the same as saying things are _impossible,_ just that they translate to real-world concepts. The square root of -1 is pretty impossible, but mathematicians still use it because it's useful in complex calculations. That's why there's a differentiation between those so-called "complex" numbers (some of which are real, some of which aren't) and just plain "real" numbers. Those are separate _branches_ of mathematics, if that's what you meant. I'm not really sure.

​@@matrixphijr You're still working in the realm of physicists and engineers, not math. Math is an entirely abstract, logical construct completely detached from physical reality. Your physical constants are merely how these things are represented in mathematical terms. They weren't devised so math could be used on them. They are the result of using math to describe these things. Math holds true because it is entirely based on logical conclusions from a set of predefined axioms. Defining a math does not mean "changing math". It means creating a new math. The regular math you're used to still exists besides it. Math is essentially a language. Defining a new math is similar to creating a new dialect. What you're calling "seperate branches" is all first semester university math. By second year a math student will already have dealt with maths way more complex than that and may well have built a simple one themself. And, uh... impossible literally means "not possible". So if you're saying something is not physically possible, you're saying it is physically impossible.

@@Llortnerof It's no wonder you compare it to a language, since you're a master of twisting words. Look, I'm not having an argument about this. You realize you responded to a comment breaking down why 2 x 5 = 10 with a bunch of rambling nonsense about creating a new system of math where you can divide by zero? And frankly, my dude, there's a reason no one's done that already -- actually, two -- because it would have no bearing on reality and therefore no use whatsoever, and honestly, no one cares. To borrow your ideology, it would be like creating a language that no one speaks.

@@matrixphijr All you're showing here is that you have a very limited understanding of math. Everything you're claiming is pointless? Has already been done, often multiple times, and at least once simply to show that it can be done. Including creating new languages nobody speaks. In fact, that's kinda the default for a newly created language since it is new and thus doesn't have any speakers yet. Hasn't stopped people from not only creating a propper grammar for, but also translating Shakespeare into its original Klingon.
