This leaves us with one simple question is 0 an integer. An integer by definition is a "counting number" or a number that is not required to be represented with a fraction/decimal. 0 can be represented with fractions such as 0/2 or 0/3 but these hold the same meaning as just 0. This is as opposed to something like 0.5 which can be represented as 1/2, 2/4, etc. but cannot be presented by a whole number. Therefore 0 is even.
