First you can only define even and odd for integers, so it only applies to {... -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...}
An integer is even if you divide it by 2 and have *no* remainder.
An integer is odd if you divide it by 2 and have a remainder.
The set of even numbers:
{... -6, -4, -2, 0, 2, 4, 6 ...}
The set of odd numbers:
{... -5, -3, -1, 1, 3, 5, 7 ...}
An alternate definition is if the last digit of a number is 0, 2, 4, 6, 8 the number is even.
If the last digit of a number is 1, 3, 5, 7, 9, the number is odd.

If a number is even it is able to be divided by 2. If it is an odd number, it cannot be divided by 2.

An odd number doesn't break even, unless you do something odd to it.
