Subject: Re: Zero as an even number

In order to define zero as even or odd, first determine the universal
set. 

If the set of whole numbers is the universal set, then simply define
an even number as an element of the set { x : x = 2n, n an element of
the set of whole numbers } and define an odd number as an element of
the set { x : x = 2n + 1, n an element of the set of whole numbers }
