2. use the order of operations to evaluate expressions. Objective The student will be able to: Designed by Skip Tyler, Varina High School

3. Why is it important to follow the order of operations? What is the correct order? Essential Questions Designed by Skip Tyler, Varina High School

4. Evaluate 7 + 4 3. Is your answer 33 or 19? You can get 2 different answers depending on which operation you did first. We want everyone to get the same answer so we must follow the order of operations.

5. Remember the phrase “Please Excuse My Dear Aunt Sally” or PEMDAS. ORDER OF OPERATIONS 1. Parentheses - ( ) or [ ] 2. Exponents or Powers 3. Multiply and Divide (from left to right) 4. Add and Subtract (from left to right)

6. Once again, evaluate 7 + 4  3 and use the order of operations. = 7 + 12(Multiply.) = 19 (Add.)

7. Example #1 14 ÷ 7 2 - 3 = 2 2 - 3 (Divide l/r.) = 4 - 3 (Multiply.) = 1(Subtract.)

8. WATCH, LISTEN, LEARNNNN Example 3: 6(4+2)^3 = ??

9. Heeeeeeeeeeelp!!!! Example 4: 18 ÷ 3 X 5 + (√25 – 2) = ??

10. INDEPENDENTLY Example 5: 5^3 ÷ 25 X 3 – 7 = ??

11. SAGE AND SCRIBE – Smallest Foot is Scribe First 1. 7(5 – 2)2. (9 + 3)^3 3. 6 X 5 ÷ 10 + 5 4. 6^3 – 18 + 24 5. √81(6^2 – 6) 6. (√36 X √169)^3
