Commutative Property: The sum or product of numbers is the same no matter how the numbers are arranged: a+b=b+a

Distributive Property: The sum of two addends multiplied by a number will be the sum of the product of each addend and the number: a(b+c)=ab+ac

Integer: The set of whole numbers & their opposites

Example:{…-2, -1, 0, 1, 2,…}

Inverse Operation: Operations that undo each other or are opposite, such as addition and subtraction

Natural numbers: Counting numbers that begin with 1.
