We cannot divide by 0.
Take the classic example:
a = b
a^2 = b^2
a^2 + a^2 = a^2 + ab
2(a^2) = a^2 + ab
2(a^2)  2ab = 2(a^2) + ab  2ab
2(a^2)  2ab = 2(a^2)  ab
2((a^2)  ab) = 1((a^2)  ab)
then divide by (a^2)  ab) to give 1 =2
The fallacy comes right at the end when dividing by 0. So, we cannot divide by zero, and 0^0 is 0/0 therefore it is Mathematically undefined.
