Algebra Review! Warm-up Take about 5-10 minutes to complete the coordinates worksheet from yesterday.

Order of Operations Objective: Students will be able to simplify expressions using order of operations. *Question: Do you know what the saying is for order of operations.

Example: Simplify the expression on your own 5∙6+8÷2 There are two different ways we could solve this problem. Which one is the correct way? Way #1 Way #2 5∙6+8÷2 30+8÷2 38÷2 19 5∙6+8÷2 30+8÷2 30+4 34

Now try this (3∙4−9)∙7 12−9 ∙7 3 ∙7 21

Multiplication Division PEMDAS Parenthesis Exponent Multiplication Division Addition Subtraction More accurately read as Parenthesis Exponent Multiplication Division Addition Subtraction

Example Simplify the expression using order of operations. 3 2 +8÷4 9+8÷4 9+2 11

Example Simplify the expression using order of operations (5+7) (1+5) 12 6 2

Working with Variables Simplify the Expression using order of operations −(4𝑥−6𝑥+7−9) − −2𝑥−2 2𝑥+2

More with Variables Simplify the expression using order of operations − 5∙2+3𝑥 +(1+9÷3) − 10+3𝑥 +(1+3) −10−3𝑥+4 −3𝑥−6

Worksheet: Order of Operations Practice Work with your group. Whatever you do not finish in class is homework.
