In the world of math, many strange results are possible when we change the rules. But there’s one rule that most of us have been warned not to break: don’t divide by zero. How can the simple combination of an everyday number and a basic operation cause such problems?

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

True
Yup
The most true thing I’ve heard in a long time
“1=2”
*years of academy training wasted*
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
Another interesting method is to use limits. If you look at a graph of 1/x, you’ll notice that the graph skyrockets up when approaching zero from the right, and plummets down when approaching zero from the left. This is because if we begin to approach zero from the right (or positive) side (by starting a 1 and then to 0.1 and then 0.01...), the answer approaches infinity. But when we approach zero from the left (or negative) side (from -1 to -0.1 to -0.01...) the answer approaches negative infinity. This means that if we were to assign a value to the graph when it reaches zero (yes I know you cannot do this), it would have to equal both positive and negative.
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
I tried something similar to this. Just as sqrt(-1) = i, I defined 1/0 as o. Then, I went as far as I could trying to figure out all the properties of this new number that I could. I had to bend quite a few rules and I still ran into a bunch of contradictions. I hope that someday, as my math knowledge grows, I can make o a number.
Can you tell me more about o?
look up wheel theory
Update for o?
Do update when you get there 🙏🏻
Your contribution will not be forgotten.
Wait, so "MATH ERROR" isn't a number ?
I feel bad for ur math teacher 😂😂
Wait this is math? I thought it was History.
So I guess there wasn't a guy called "Infinity" who discovered Amerika...
Wait...wasn’t the guy who discovered america called pi?
No, that one discovered space.
You've got it all wrong. Syntax error discovered the earth, and many many years in the future pi found the continent now known as "America". Before that, there was already "i"'s all over America, but they didn't count since they were technically imaginary. But nowadays, if you take 1 apple and eat 2 of it then you can take what's left (-1 apple) and use it's square root to bring back an i. However, this is highly illegal so don't credit me as the one who told you.
(PS: MATH ERROR was the creator of earth)
Nice try, but we all know
0 ÷ 0 = ERROR
no. is 1

This can also very nicely be explained by using a y = 1/x graph. Where x approaching from positive x-axis to 0 gives us an Infinitely large positive number. While x approaching from negative x-axis to 0 gives us an infinitely large negative number. And 1/0 cannot be both positive and negative infinity at the same time.
so it’s ♾️
10 ÷ 0= 0
Why can't it be both

If we have 1 cake and multiply it by 0, it means we made cacke disappear. If we divide 1 cake by 0 that means we divide cacke by nothing, we made division dissapear, defeating the whole purpose of dividing it. So its equasion that allways defeats its own purpose, its a non starter. Nothing happens if you divide by 0 because division can never start because it cancels itself.

@@sainbaatar518 No he is talking about 0÷0. 0÷X is always 0. If you were to divide, say 2 by 0, you can never multiply 0 to get to 2. You would never share the 2 to anyone, and if you are inversing the multiplication to get 2 ÷ 0, you never had the 2 in the first place, so you couldn't possibly share it. You get caught in a loop, which is infinite, and I think that is why the logistical conclusion people come to when dividing by zero is infinity.

I accidentally divided by zero while doing homework when exhausted. My whole notebook burst into flames.
Basically, the dividend is the Y on a graph and the divisor is the X. Since Y is the dependent variable, it can only change value if X changes value. If X changes and Y doesn’t, than that is okay (0/1=0) however if Y somehow changes without X, than the laws have been broken. Therefore 1/0 =0. The reason Y is the dividend and X is the divisor is because Rise/Run is the slope of a line. You can have a line with 0 slope, but not a line going straight up forever. It would be the same as just a dot.

Yet another example that explaining "why", is the best way to teach.
honestly, it's because the answer is always the numerator, since you are dividing by nothing, which gives it the top number always. just like anything divided by 1
The definition of dividing a/b, is finding a number c such that b*c = a. (it’s actually a bit more complex but this definition helps for now). For example, 8/2 = 4, because 4*2 = 8.
If you take 8/0, there’s no number that gives you 8 when multiplied by 0. So division by 0 is not defined.
I was wondering why they didn't just make new rules. 3 minutes in and my hopes and dreams are crushed XD
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. If you disagree with my use of exponential notation, my algebraic logic is still sound.)

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
@@skullmastergamer wow. Amazing that u gave me all that info and I STILL know nothing about infinity
For me it make sense if you write it differently, not “infinity = 1/0” but “0=1/infinity “ essentially the same but solves the problem with 1=2 cause there will be 2/infinity
Another issue with defining division by zero to be infinity involves rational functions where one side of the limit approaches infinity and the other side approaches negative infinity.

“Imagine you have zero cookies and you split them among zero friends how many cookies does each person get? See?
It doesn’t make sense, and cookie monster is sad that there are no cookies, and you are sad because you have no friends.”
Hi Siri
Nah
We can split infinite zero cookies among infinite zero friends
It is simple:
0 / 0 = 0
Ace Kermitcat nice the Siri line of when you ask her what’s 0 divided by 0?
When I was a kid, I used to think the following to explain why can't we divide by 0: "If little Timmy has 10 gums to share between 0 people, how many gums would little Timmy have?" I know that this is not an actually correct way to explain it, but I really liked how it creates a logical and even philosophical problem. Does Timmy even exist? The gums surely do, and they have to go to someone, but who if there is nobody to receive them? Math is really really interesting

I think if anything divided by zero is infinity. Zero is nothing. But I think nothing can be anything thus becoming anything. Idk why I thought of that, but I really do think that nothing can be anything.
When he started talking about what multiplication and division _are,_ I thought he was going to touch on how if 2 x 5 = 10 and 10 ÷ 5 = 2, that means that if you add 2 five times, or have five groups of 2, you have 10, and if you separate 10 into 5 groups, you have 2 in each. So if you want to divide 10 by 0, that would be like saying you want to split 10 things into groups with 0 in them, and how many groups do you have? Or in reverse, how many groups of 0 things would it take to add up to 10? Well, neither one is physically possible.
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.

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.
Nothing can equal infinity, because infinity is not a number, but a concept. You can approach infinity, but you can't reach it because it isn't a real number.
say something new, 'cause my maths teacher has told me that infinite times
Infinite is a concept of how numbers wont stop or u can say forever

I sometimes get a bit of amusement out of testing how various caculators respond to division by 0. Most just say "Error", but my favourite response has to be "MyScript Calculator", which uses hand-drawn symbols as input:
The app recognises hand-drawn symbols and translates them to computer-written symbols, but when I write something like "0/0", it autocompletes to "0/(0+?)", as if the calculation is incomplete. Basically, the app just assumes that I'm not done writing the expression, and refuses to give any answer until I do. It makes the app seem so sassy.
"Oh, you have a 0 in the denominator? Well, that doesn't make any sense, so you MUST not be finished writing yet. Go ahead and write some more. I'm waiting."
Love that
That's because of discrete maths, a computer can't divide by 0 (basically if you have the algorithm will go into an infinite loop, and the quotient will grow larger and larger until it exhausts all available memory and your computer is going to die), so basically it's a way to prevent an error and the destruction of your device haha
hilarious
Lol awesome
Sounds like your calculator is related to KITT

Not sure if bait, but limits of functions that divide by 0 are used everywhere in calculus, explicitly or not.
If you could divide by zero you could do this:
5*0=0
7*0=0
5*0=7*0 |÷0
5=7
And that doesn't make any sense.
Yet the video said 1=2 COULD be possible so what's so implausible about 5=7? Also, say infinity is every number all at once for the sake of argument. Then that means 5= infinity and 7 = infinity which means 5=7 is rather infinity = infinity which makes sense right?
It’s like saying 0x0=5
But u just divided by 0 to eliminate the 0...
0 ※ 0 = ⇔
Do not forget BODMAS.

I'm impressed that you're able talking about 1/0 without mentioning limit even once
Well, approaching 0 and reaching 0 are two different things
@@milandavid7223 yeah. But one way to define a calculation is by knowing its limit. For example lim (x->0) 1+x = 1, so we can say that 1+0=1
But for 1/0, it has upper limit and lower limit so different (inf, and - inf) so it has no limit. Or in other word, 1/0 can NOT be defined
