7
Parentheses The first step of the order of operations is parentheses. Ex. (3 x 6) = 18 Ex. (3 x 6) + 2 = 20 18 + 2 = 20

8
Exponents The second step of the order of operations is exponents. Ex. (3 + 2) 2 = 25 5 2 = 25 Ex. 3 + (3 + 2) 2 = 28 3 + 25 = 28

9
Multiplication The third step of the order of operations is multiplication. Ex. 6 x 4 = 24 Ex. (3-2) 2 x 4 = 4 1 x 4 = 4

10
Division The fourth step of the order of operations is division. Ex. 8 ÷ 2 = 4 Ex. 8 ÷ 2 + (3 x 6) = 22 4 + 18 = 22

11
Addition The fifth step of the order of operations is addition. Ex. 3 + 6 = 9 Ex. 3 + 4 ÷ 2 = 4 3 + 2 = 4

12
Subtraction The last step of the order of operations is subtraction. Ex. 16 – 4 = 12 Ex. 18 – (2 + 2) 2 = 2 18 - 16 = 2

13
Practice (3 + 5) 2 – 2 =28 – 3 2 x 2 = 3 + 8 ÷ 4 + 12 = (3 + 5) – 2 = Answers Copy the following problems into your notebook and practice them.

14
Practice 4 2 + (2 x 5) x 3 – 6 ÷ 2 = Answers Copy the following problems into your notebook and practice them. (3 x 2) 2 ÷ 5 – 3 + 4 =

17
Quiz (3 x 2) 2 x 4 ÷ 2 + 3 2 – 4 = Copy the following problems on a piece of paper and hand them in when you are done. (12 + 2) – 12 ÷ 2 2 x 1 = Answer

18
Practice Answers (3 + 5) 2 – 2 = 62 8 2 – 2 = 62 64 – 2 = 62 28 – 3 2 x 2 = 10 28 – 9 x 2 = 10 28 – 18 = 10 3 + 8 ÷ 4 + 12 = 17 3 + 2 + 12 = 17 5 +12 = 17 (3 + 5) – 2 = 6 8 – 2 = 6

19
Practice Answers 4 2 + (2 x 5) x 3 – 6 ÷ 2 = 43 16 + 10 x 3 – 3 = 43 16 + 30 – 3 = 43 46 – 3 = 43 (3 + 2) 2 ÷ 5 – 3 + 4 = 6 5 2 ÷ 5 – 3 + 4 = 6 25 ÷ 5 – 3 + 4 = 6 5 - 3 + 4 = 6 2 + 4 = 6

20
Quiz Answers 12 x 2 – 4 x 6 = 0 24 – 24 = 0 (12 + 2) – 12 ÷ 2 2 x 1 = 21 24 – 3 x 1 = 21 21 x 1 = 21

21
Quiz Answers (3 x 2) 2 x 4 ÷ 2 + 3 2 – 4 = 77 36 x 2 + 9 – 4 = 77 72 + 5 = 77 (12 + 2) – 12 ÷ 2 2 x 1 = 11 14 – 3 X 1 = 11 14 – 3 = 11
