      I would also go mad if I had to accept that 83 is a prime number but 1 isn’t

          what i’m mad about is that you can divide by infinity and get zero, but you can’t divide by 0 and get infinity. make up your minds maths people

            Oh you totally can (as long as you’re working with implied limits, which you have to if infinity is in the mix), you just have to specify if it’s a positive or negative zero.

                i mean, implicitly it’s just whether you’re approaching zero from positive or negative direction, since we’re working with limits.

                Like you can shave down a stick however much you want, you can never reach 0 stick by doing so.
