Evaluating Algebraic Expressions
• Evaluate each expressions for the given value of x.

21 – x +2 • 5 for x = 7 for x = 24

Evaluating Algebraic Expressions

Your Turn!

for x = 2 for x = 6

Simplifying Expressions (grouping symbols)
• Absolute values: treat like parenthesis
• Division: treat the numerator like it is in parenthesis and

the denominator like it is in parenthesis

Translating from Words to Math
• Translate each word phrase into a numerical or algebraic expressions.
• One half times the difference of -5 and 3
• The square root of the quotient of -12 and n
