Algebra 2 Foundations, pg 20 “An expression that is a number a variable, or the product of a number and one or more variables is a term. A coefficient is the numerical factor of a term. A constant term is a term with no variables. You can add terms to form longer expressions. The expression below has three terms.  To evaluate algebraic expressions  To simplify algebraic expressions

Algebra 2 Foundations, pg 21  To evaluate algebraic expressions  To simplify algebraic expressions “You can simplify an algebraic expression that has like terms. You combine like terms using the properties of real numbers (Lesson 1-2). An expression and its simplified form are equivalent. Their values are equal for all values of the variables. Simplify the above expression.
