Essential Questions

Designed by Skip Tyler, Varina High School

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.

Remember the phrase“Please Excuse My Dear Aunt Sally”

or PEMDAS. ORDER OF OPERATIONS1. Parentheses - ( ) or [ ] 2. Exponents or Powers3. Multiply and Divide (from left to right)4. Add and Subtract (from left to right)

Once again, evaluate 7 + 4 3 and use the order of operations.

= 7 + 12 (Multiply.)= 19 (Add.)

Example #1

14 ÷ 7 • 2 - 3 = 2 • 2 - 3 (Divide l/r.) = 4 - 3 (Multiply.)

= 1 (Subtract.)

WATCH, LISTEN, LEARNNNN

Example 3: 6(4+2)^3 = ??

Heeeeeeeeeeelp!!!!

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

INDEPENDENTLY

Example 5: 5^3 ÷ 25 X 3 – 7 = ??

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
