## Is zero an even number?

The use of the phrase “even number, or the number zero” implies that zero is not even. On the other hand, the mayor is lumping zero together with the even numbers, so he certainly doesn’t think it’s odd. So what is it – odd, even or neither? For mathematicians the answer is easy: zero is an even number.

## Why is zero not positive or negative?

0 is the result of the addition of an element (x) in a set with its negation (−x). … However, by definition, the given set must have a negative element for all the positive elements. Therefore, it makes no sense to conceive it as a positive number. Hence, 0 is neither positive nor negative.
