A root of a function is also sometimes known as “a zero of .”

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?
