- 1. Order of Operation s Georgia Performance Standard M4N7b: Compute using the order of operations, including parentheses. Created by D. Guest-Johnson 2008
- 2. Order of Operations are rules that you must follow when solving expressions. Created by D. Guest-Johnson 2008
- 3. 1st- Parenthesis 2nd- Exponents 3rd- Multiply and Divide from Left to Right 4th- Add and Subtract from Left to Right Created by D. Guest-Johnson 2008
- 4. We can remember the Order of Operations using PEMDAS! What is PEMDAS??? •Please- Parenthesis •Excuse- Exponents •My Dear- Multiply and Divide •Aunt Sally- Add and Subtract •PEMDAS Created by D. Guest-Johnson 2008
- 5. • 1st-Parenthesis • Solve anything that is in parentheses first! • example: (8+ 4) • example: [5 + -6] Created by D. Guest-Johnson 2008
- 6. • 2nd-Exponents • Solve anything that is an exponent second • example: 23 = 2 x 2 x 2 = 8 • example: 34 = 3x3x3x3=81 • So What is : 45 ? • 4 x 4 x 4 x 4 x 4 = 1024 Created by D. Guest-Johnson 2008
- 7. • 3rd-Multiply and Divide • Always multiply and divide from Left to Right • example: 3 x 4÷2 = 12/2= 6 • example: 8÷2 x 4 = 4x4=16 Created by D. Guest-Johnson 2008
- 8. • 4th-Add and Subtract • Always add and subtract from Left to Right • example: 5+4–3 = 9 -3=6 • example: -4+6-10 = 2-10=-8 Created by D. Guest-Johnson 2008
- 9. Try This! • 6-3÷3x2+3 • 6–1x2+3 • 6–2+3 • 4+3 •7 Created by D. Guest-Johnson 2008
- 10. Try This One! • 23 + (5 + 3) x 3 ÷ 2 • 23 + 8 x 3 ÷ 2 • 8+ 8 x 3 ÷ 2 • 8+ 24 ÷ 2 • 8+ 12 • 20 Created by D. Guest-Johnson 2008
- 11. Challenge You to This One! • [8- (3 x 2) +3] – 22 ÷2 • [8- 6 +3] – 22 ÷2 • [2 +3] – 22 ÷2 • 5 – 22 ÷2 • 5 – 4 ÷2 • 5–2 • 3 Created by D. Guest-Johnson 2008
- 12. What would happen if you did not follow the order of operations rule when solving math problems? To remember the rule, just think of Please Excuse My Dear Aunt Sally! 1st- Parenthesis 2nd- Exponents 3rd- Multiply and Divide from Left to Right 4th- Add and Subtract from Left to Right Created by D. Guest-Johnson 2008
