A. Associative Property

The Commutative Property states that changing the order of the numbers in an operation does not change the result. For example, a x b = b x a.

The Associative Property states that the way in which numbers are grouped in an operation does not change the result. For example, (a + b) + c = a + (b + c).

The Distributive Property states that a(b + c) = ab + ac. It allows you to multiply a number by a sum.

A factor is a number that divides another number without leaving a remainder. For example, 2 and 3 are factors of 6.

A composite number is a positive integer that has at least one positive divisor other than one or itself. For example, 4, 6, and 8 are composite numbers.
