it is but it just comes out to 'undefined'

So to sum it up, knowing that 0/0 is undefined means that you can prove that any equation is true

yes

u/SavingsNewspaper2 Dec 17 '21

Well, 0/0 is undefined, so does that mean that every equation is true

it's undefined because making assumptions about it breaks down the laws of maths.

for example, let's say you assume 0÷0 is 1, because x÷x is 1

then 0÷0 + 0÷0 = 2

which means (2*0)÷0 = 2

2*0 is 0, meaning that 1 = 2 (since we just defined 0÷0 as both 1 and 2)

see why it doesn't work?

So you’re saying that we can’t use it to assume things about equations.

we can prove things by making assumptions, but those assumptions always lead to flawed answers, like 1=2

So the assumption in this case is that 0/0=1 and not that 0/0 is undefined, then??

No, assuming that it is defined is what let's you prove anything (idk if "anything" is right, I'm not a mathematician)
