There are 4 properties of multiplication

3.(multiplicative) Identity - The product of any number and 1 is that number itself. 3 x 1 = 3

4.Distributive - The sum of two numbers times a third number is equal to the sum of the product of each addend with the third number 5 x (2+4) = (5x2) + (5x4)

Aprime number is a whole number greaer than 1 that has exactly two factors, 1 and itself of the numbers.

A composite number is a whole number greater than 1 that has more than two factors.
