Subject: Re: Re: Dividing by zero

In the first part of your reasoning, you suppose that a/0 = 0 . You
cannot do that. You are taking an arbitrary decision.

Then you say that 0/0 = a and 0/0 = b and that it would mean a = b .
It doesn't necessarily mean this. By reasoning like that I can also
prove that square root should be an undefined operation :
sqrt(1) = 1  and  sqrt(1) = -1 , therefore 1 = -1 which is not
possible.
