Inverse Property of Addition (Additive Inverse) Math Poster

In this lesson, students use the inverse operation for multiplication and division in order to solve for linear equations. They also employ the reciprocal when addressing fractional coefficients in these equations. The properties of Equality are a portion of the lesson, , including the Addition Property of Equality, the Subtraction Property of Equality, the Multiplication Property of Equality, and the Division Property of Equality.

Positive and Negative numbers are added using both the vertical and horizontal number lines; the rules of addition in algebra are introduced, as well, and students apply these rules to calculations. Properties (Closure for addition, commutative, associative, Identity, and inverse) are presented with a discussion as to how these properties relate to operations of addition.
