Vocabulary to knowA term is an algebraic expression that is a

single number, a single variable, or the product of numerals and variables.

Examples of terms:

125 (a single number)

x (a single variable)

125xy (the product of numerals and variables)

Vocabulary to knowThe number of terms in an expression can help you

name the expression. Terms are connected with + or – signs.

Monomial – has one term, example: 125xy

Binomial – has two terms, ex: 125xy + 4

Trinomial – has three terms, ex: 125x - 4y + 3

Polynomial – has two or more terms,

Examples: 2x + 3 and 5x + 7y + 9z – 4

Objective- To use the distributive property to

simplify variable expressions.

Distributive Property

a(b + c) = ab + acor

a(b - c) = ab - ac

Order of Operations Distributive Property
