This document provides instruction on the order of operations for solving mathematical expressions. It explains that there are specific rules to follow when solving expressions, known as the order of operations. These rules are: 1) complete all operations within parentheses first, 2) perform all exponents next, 3) multiply and divide from left to right, and 4) add and subtract from left to right. The document provides examples of solving expressions using the proper order of operations and encourages remembering the order using the acronym PEMDAS.

5. • 1st-Parenthesis
• Solve anything that is in
parentheses first!
• example: (8+ 4)
• example: [5 + -6]

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

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

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

• 23 + (5 + 3) x 3 ÷ 2
• 23 + 8 x 3 ÷ 2
• 8+ 8 x 3 ÷ 2
• 8+ 24 ÷ 2
• 8+ 12
• 20

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

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
