RafaIf its even its in the 2x table and if its odd its not in the 2x table,so that means its an odd 'cause its not in the 2x table.
The easiest way to test if a number is odd of even is to look at its last digit.
If it is divisible by 2, that is one of {0, 2, 4, 6, 8}, then the number is even;
If it is not divisible by 2, that is it is one of {1, 3, 5, 7, 9], then the number is odd.
The last digit of 15 is 5, so it is an odd number.

By addition, the sum of an odd number and an even number is always odd. (3 + 2 = 5, 7 + 10000 = 10007 ~ not evenly divisible by 2) By multiplication, an odd number times an even number is always even. (3 x 4 = 12 , 15 x 30 = 450 ~ evenly divisible by 2)
