0/0 = undefined

There is a bit cheaty way to prove that 0/0 = 2 :D

And what's that?

If you plot the line y = x, if you divide y by x for every point on the line, you get 1, this includes the point (0,0), which means 0/0 = 1. If you repeat this but with the line y = 2x, every point on the line gives you 2 if you divide y by x, including (0,0). By using a different line, you can make 0/0 equal anything you want, which is why it is undefined.

0/0=
100-100 / 100-100=
(10)^2 - (10)^2 / 10*(10-10) =
(10-10) (10+10) / 10*(10-10) = (shorten it up by (10-10)
(10+10) / 10 =
20/10 =
2/1=
2

Dont know if our teacher told us shit but he said that Thing where you put it to (10-10) (10+10) is working. I didnt believed him but he says it works.

That doesn't really make sense.. at least not in the way I was taught.

Well those are all things that work of what I got taught except the (10-10) (10+10)

Euh 10^2 = 10×10 as far as I know xD

teacher told us shit confirmed

it doesn't work. you can't divide both sides by (10-10) because that's equal to 0; that's not allowed in algebra. using a similar method to what I said above, you can make anything divided by 0 equal anything, therefore it doesn't work.
