: Given x^2 + y^2 = 0, x and y nonzero integers, show that no solution
: exists.

: Proof by contradiction:

: (x+sqrt(-1)y)(x-sqrt(-1)y) = x^2 + y^2 = 0, so

: x = sqrt(-1)y *or* x = -sqrt(-1)y.

Still waiting for an explanation of this step.

: There doesn't exist an integers that multiplies times itself to give a
: negative number, and an integer can't be the product of an integer and
: a non integer, so there's a contradiction.

An integer *can* be the product of an integer and a non-integer.
2 * 0.5 = 1.

So, your proof of this simple fact still needs work.
