I'm no number theorist, but I would say -1 ; -3 ; -5 ; ... is odd, while -2 ; -4 ; -6 ; ... is even.

EDIT: Zero is also defined as an even number.

For negative numbers, it works just like positive numbers.

0 is even because it is a multiple of 2 : the remainder of 0 in the division by 2 is 0..

I hope this clears out the problem.. ?

4. A number is even iff $x = 2n$ for some $n\in \mathbb{Z}$. Of course $0 = 2(0)$.
