The Order of Operations

2. Warmup #1 Find the product of 4 and 5.
#2 Find the quotient of 18 and 2.
#3 Find the sum of 10 and 24.
#4 Find the difference of 20 and 13.

3. With subtraction, order matters.
5−2 𝑎𝑛𝑑 2−5 are different.
If there are several operation symbols in an expression, there is a specific order to follow.

4. 1st Work inside parentheses
2nd Exponents
3rd Multiply and Divide from left to right
4th Add and Subtract from left to right

7. Simplify
6 2+5 −10
Write the expression.
Do ONE step on each line. Write the letter(s) of the operation P,E,MD,AS
Work each line DOWN the paper.

8. 6 2+5 −10
6 7 − P
42− MD AS

9. Try these #1 6+12÷3−2 (3 steps) #2 11+2 15÷3 −1 (4 steps)

10. #1
6+12÷3−2
6+4− MD
10− AS AS

11. #2
÷3 −1
− P
11+10− MD
21− AS AS

12. #3
14−6∙2+18÷3
14−12+18÷ MD
14− MD AS AS

13. If there is a fraction in a problem, put parentheses around the numerator or denominator if there is an operation symbol.
The line of the fraction always means to divide
= =5

14. Compare the two expressions using >, < or =.
8+3 10÷2 +3∎45−7(1+3)
Simplify each expression using order of operations!

15. 8+3 10÷2 +3∎45−7(1+3)
−7 4
−28 26

16. Inserting parentheses can change the answer.
Insert parentheses to make this number sentence true.
16−6÷2=5

17. Write a numerical expression and simplify
#1 Six plus the product of ten and four
#2 Eight minus the quotient of twenty and four.

18. #1 6+(10∙4)
6+40 46
#2 8− 20÷4
8−5 3

19. Write an expression to find the area
