(0 + odd number) + (0 + even number)
odd number = 1
even number = 2

(0 + 1) + (0 + 2) = ?
1 + 2 = ?
3

odd number = 3
even number = 2

3 + 2 = 5
5

1ODD + 1EVEN = AN ODD NUMBER
So basically:
E + O = Odd
O + E = Odd

E + E = Even
O + O = Even

It also applies in multiplication:

(-)(+) = -
(+)(-) = -

+ * + = +
- * - = +
