There are 4 properties of multiplication 1.Commutative - When two numbers are multiplied, the product is the same regardless of the order of the factors. 5 x 4 = 4 x 5 = 20. means factor1 x factor2 = factor2 x factor1 2. Associative - When three or more numbers are multiplied the product is the same regardless of the grouping of the factors. (2 x 3) x 5 = 2 x (3 x 5) 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)

A prime 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.

2 is the only even prime
