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
