This is because computers don't use real real numbers.
They use something, which can't be called algebra either.
So you can't imply anything from anything. Sorry.

I would like to see it, at least since I still don't believe in
your +/- zeroes.
At least they can't give infinite after division, when they are
not real zeroes.
