It doesn't make sense.

Let's take 5 divided by zero. That's obviously equal to 0, since 5 * 0 equals zero.

First, you would then at least have ONE group and second it isn't really consistent, since saying sth. Like "divide into zero groups" does not make sense whatsoever yet alone the concept of size inside a non existent group.

The only way I can wrap my head around it is if I just subtract the first from the second, if the second is larger and the first is negative, but I KNOW this isn't how it works.I came across this problem while looking at a solution for simplifying a rock paper scissors script in python using dictionaries and keys.I didn't understand how or why modulus could be used to eliminate all the conditionals and relegate it to one line to determine whether user input won.tl:dr How does modulus actually work with negative numbers? I can't understand the actual reason, even though I know a brain dead solution.

It does, and it's infinity.Infinity is very inconvenient to work with (seeing as it isn't a number) and a division that doesn't have a multiplication as its inverse is also very inconvenient. For these reasons, mathematicians often prefer to say "fuck it. We'll just avoid doing it, because it's not worth the trouble".And I agree, it really isn't worth the trouble. But that doesn't mean it doesn't exist or doesn't make sense. It does and it does.

 >> Anonymous Fri May 4 16:46:20 2018 No.9718729 Holy fuck people. Division by an x is defined as a multiplication by the inverse of x. The inverse of x is defined as y such that x*y=1.But, if x=0 then x*y = x*0 = 0 for any y. So there is no inverse for 0.That's why division is not defined for 0. It's a matter of definitions. Feel free to define your own way multiplication, but then you probably can't use a lot of the math we have proven so far.

This is just one of many many examples of infinite summation being retarded because infinity is retarded and treated as a number in higher math, when it really really really really isn't even relateable to numbers at all; being unable to perform any similar function that real numbers and even imaginary numbers can. Even this example would show that in arbitrary unreal time where infinity could be achieved, doing so invents termination, thus $0.\overline{9}$ truly is not the same number as 1. This is further shown through the implication that the infinite property of the sum truly should mean "unending", which also means there exists no decimal cutoff of accuracy and implies a requirement of infinite arbitrary decimal places that need to be filled. For 7 decimal places, would you say [0.9999999] is equal to 1?For 2 decimal places like with dollars, would you say 0.99 is equal to 1?No. Of course not. You accept that there is always some small remainder, but you get retarded about infinity and deny a small remainder can exist there too.0.99] 99 cents is not 1 dollar0.999] 999 grams is not 1 kilogram0.999...] $0.\overline{9} \neq 1$

Converging to any number is retarded and easy, even though converging to a number under "infinite" summation is just mapping a divergence towards infinity to towards a number, but the base mechanics dont change. It never teaches infinity in divergence and it never reaches the limit in convergence.

Which is exactly $\frac{1}{3}$. Perhaps that's where you're having trouble? That sequence does never reach $\frac{1}{3}$ but it's limit is $\frac{1}{3}$. Good on you for questioning what's presented and thinking about infinity, but the symbol is defined to be the limit.
 >> Anonymous Tue May 8 06:36:49 2018 No.9726412 >>9726390Let me explain it another way. $.\bar{9}$ is defined to be that very same number a finite string of 9s never reaches, which is the number 1. Therefore when we write $.\bar{9}$ we mean the number 1. So you can maintain your intuition that it never quite reaches 1 while still accepting that its limit is 1, and we're speaking in terms of limits when we invoke infinity, whether it's with bars or dots

Maybe we need to expand our notion of a "number" yet again to unify physics (ToE)?Is the formal symbol for divide-by-zero considered "infinity" or is it considered meaningless? If not, does it make any sense to adjoin x/0 to the number system in a more formal way, a more useful way? If not this either, is there some other meaningful way we can extend our number system?

So yea, there are some ways math could change sure, but they involve getting away from infinity outright. Also since the internet has come about, rate of prestablished information being positively change has decreased. We're sooner to lose all higher maths than infinity as liberal for profit universities go full communism to indoctrinate their students with intentionally bad math supportive of fringe foreign government policies, which will eventually become no math at all with the increased reliance on "smart" devices and generations of learning about how much money you're entitled from the government.outlook is grim. also zero + infinity just look like a dick and balls.$\rlap{\; \text{0}}{\infty}$
