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

6. Exponents The second step of the order of operations is exponents.á
52 = 25
Ex. 3 + (3 + 2)2 = 28 á
= 28

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

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

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

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

Answer

15. Practice Answers (3 + 5) – 2 = 6 8 – 2 = 6 3 + 8 ÷ 4 + 12 = 17
= 17
5 +12 = 17
28 – 32 x 2 = 10
28 – 9 x 2 = 10
28 – 18 = 10
(3 + 5)2 – 2 = 62
82 – 2 = 62
64 – 2 = 62

16. Practice Answers 42 + (2 x 5) x 3 – 6 ÷ 2 = 43 16 + 10 x 3 – 3 = 43
– 3 = 43
46 – 3 = 43
(3 + 2)2 ÷ 5 – = 6
52 ÷ 5 – = 6
25 ÷ 5 – = 6
= 6
2 + 4 = 6

17. Quiz Answers
12 x 2 – 4 x 6 = 0
24 – 24 = 0
(12 + 2) – 12 ÷ 22 x 1 = 21
24 – 3 x 1 = 21
21 x 1 = 21
(3 x 2)2 x 4 ÷ – 4 = 77
36 x – 4 = 77
= 77
