Properties

Zero Proptery

The zero property states that whenever zero is a factor in a multiplication problem, the product will always be zero.

Communative Property

The commutative property states that changing the order of the factors in a multiplication problem will not change the product.

Distributive Property

The sum of two numbers multiplied by a third number is equal to the sum of each addend multiplied by the third number.

Example:

a(b+c) = (ab) + (ac)

Identity Property

The identity property of multiplication states that when any real number (we will say "r") is multiplied by 1, the real number is always the answer. r X 1 is ALWAYS r.
