Zero is EVEN, People!!

My kids are watching a math show about odd and even numbers. They are showing the numbers 0 through 9 and saying 1, 3, 5, 7, and 9 are odd, but only 2, 4, 6, and 8 are even. I don't know why this pisses me off so badly today, but 0 is an even number too, and yet they're not including it. I couldn't begin to tell you how many people there are out there who think 0 is neither odd nor even.

People, zero is even. Even integers are those that can be represented as 2n where n is an integer, and when n=0, you get 0 as an even number. You can make a case that 0 is not even, if you only allow n to be a natural number (1, 2, 3, ...), but since that set is closed under addition and 0 is not in it to begin with, it's sort of a moot question.

Zero is neither positive nor negative, but it is definitely even.
