Is zero divisible by zero? - eviltoast

Seems like it should and the result should be one. Does mathematics agree with me on that?

    It does not. If you enforce 0/0=1, then you end up in a situation where you can prove any two numbers are equal to each other and you end up with a useless system, so we do not allow for that.

    e.g. 0=0*2 -> 0/0 = (0/0)*2 -> 1=1*2 -> 1=2

    If you get into calculus though, you’ll have ways to deal with this to some extent using limits.

        Thanks. I already fixed it, but it seems Lemmy is just slow to propagate edits.

      I see you replace two “0” with a “0/0”, but why that? Since you assume it equals 1, why do you replace it for 0?

          Ah, yes. Normally not allowed because undefined, but here you define it as 1. Alright, thanks.
