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

What are the rules of multiplying negatives and positives?
positive X positive = positive positive X negative = negative negative X positive = negative negative X negative = positive
What are the laws of exponent when multiplying monomials?
When multiplying monomials, the exponent rules depends on its placement. For example, (3x)^2 would be 9(x^2). However, 3x^2 is simply 3(x^2). (xy)^2 means you have to use the F.O.I.L. method, meaning x*x + x*y + y*y, or x^2 + xy + y^2.
When multiplying a number with exponents do you add or multiply the exponents?
You add exponents when multiplying. Ex: (xm) × (xn) = xm+n
What are the rules in multiplying integers?
Let's use N to represent any number.N x N = NN x -N = -N-N x -N = NSo the rules are:A positive integer times a positive integer will be a positive integerA positive integer times a negative integer will be a negative integerA negative integer times a negative integer will be a positive integer.
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.)
