1 WARM-UP

2 LESSON 16: SIMPLIFYING AND EVALUATING VARIABLE EXPRESSIONS Expressions and Equations

3 A NOTE ON TAKING NOTES… For today, ALL the examples MUST be in your notes. Make sure you write the initial problem down. They will be in PINK.

4 EVALUATING EXPRESSIONS To evaluate an expression that contains variables, substitute the value for each variable, then simplify We can also simplify the expression with the variables and then substitute the values.
