Same as Total Makes Is

Writing Algebraic Expressions Write each as an algebraic expression. 1. the sum of 5 and 7 2. the product of n and 6 3. 4 fewer than 9 4. 6 squared 5. One third of 12 6. the difference of 19 and 14 7. the quotient of 6 and 2

Writing Verbal Expressions Write each as a verbal expression. 1) 8 + n 2) 5x 3) 9 – 2 4) 5) 9³

Writing then evaluating Evaluate each expression. 1) 7 squared 2) 19 more than 6 3) 7 fewer than 11 4) the quotient of 6 and 12 5) twice 8

Order of Operations: 1. Parenthesis/ Grouping Symbols: Evaluate inside symbols such as ( ), [ ], { } 2. Exponents 3. Multiplication/Division: Left to Right 4. Addition/Subtraction: Left to Right

Find the value of the following.

A little vocab… Variable: symbols, usually letters, that represent unknown values Numerical expressions: consists of numbers, operations, and grouping symbols. Algebraic expressions: expressions that contain at least one variable Evaluate an Expression:
