I'm no expert but I'm guessing this may help you...
odd x odd = odd
even x even = even
odd x even = even
for negatives and positive multiplying...
n x n = p
p x p = p
n x p = n
i hope this helps you!
another thing that works is halving and doubling for example:
16x15=240
8x30=240
4x60=240
2x120=240
1x240=240

How you could use doubling to find the product 13 X 4?
Doubling a number is equivalent to multiplying by 2. Doubling twice (doubling, and then doubling the result again) is equivalent to multiplying by 4. (Also, doubling three times is the same as multiplying by 8, doubling 4 times is the same as multiplying by 16, etc.)
