6th Grade Order of Operations Worksheets - Free Printable

Let’s solve each problem step by step, following the order of operations:
Parentheses → Exponents → Multiplication and Division (left to right) → Addition and Subtraction (left to right)

---

1) 4 + 7 × 3 – 6
First, multiply: 7 × 3 = 21
Then: 4 + 21 = 25; 25 – 6 = 19

2) (7 + 11) ÷ 3 – 5
Parentheses first: 7 + 11 = 18
Then divide: 18 ÷ 3 = 6
Then subtract: 6 – 5 = 1

3) 9 × (8 – 5) + 6
Parentheses: 8 – 5 = 3
Multiply: 9 × 3 = 27
Add: 27 + 6 = 33

4) 6 – 2 × 5 + 8
Multiply first: 2 × 5 = 10
Now left to right: 6 – 10 = -4; -4 + 8 = 4

5) 8 × 5 ÷ 4 – 9
Left to right for × and ÷: 8 × 5 = 40; 40 ÷ 4 = 10
Then: 10 – 9 = 1

6) 4 – 7 × (5 – 3) + 6
Parentheses: 5 – 3 = 2
Multiply: 7 × 2 = 14
Now: 4 – 14 = -10; -10 + 6 = -4

7) 30 – (10 – 8) × (4 + 3)
Parentheses: 10 – 8 = 2; 4 + 3 = 7
Multiply: 2 × 7 = 14
Subtract: 30 – 14 = 16

8) 4 × 8 – 7 × 6
Multiply both: 4 × 8 = 32; 7 × 6 = 42
Subtract: 32 – 42 = -10

9) ½ × (12 + 6) – 4
Parentheses: 12 + 6 = 18
Multiply: ½ × 18 = 9
Subtract: 9 – 4 = 5

10) 8 × (¾ + ¼) – 5
Parentheses: ¾ + ¼ = 1
Multiply: 8 × 1 = 8
Subtract: 8 – 5 = 3

11) (5 + 4)²
Parentheses: 5 + 4 = 9
Exponent: 9² = 81 → 81

12) 5² – (3 + 2)²
Exponents and parentheses: 5² = 25; (3+2)=5 → 5²=25
Subtract: 25 – 25 = 0

13) ½ × (23 – 9) + ¼ × (15 – 7)
Parentheses: 23–9=14; 15–7=8
Multiply: ½×14=7; ¼×8=2
Add: 7 + 2 = 9

14) 18 ÷ (2² + 5)
Exponent: 2² = 4
Parentheses: 4 + 5 = 9
Divide: 18 ÷ 9 = 2

15) (6² + 12) ÷ (3² – 1)
Exponents: 6²=36; 3²=9
Parentheses: 36+12=48; 9–1=8
Divide: 48 ÷ 8 = 6

16) ¾ × (5 + 12 ÷ 4)
Inside parentheses: 12 ÷ 4 = 3; then 5 + 3 = 8
Multiply: ¾ × 8 = 6 → 6

17) (3² – 7) × (2² + 8)
Exponents: 3²=9; 2²=4
Parentheses: 9–7=2; 4+8=12
Multiply: 2 × 12 = 24

18) 7 × 5 – 4 × 6 + 3 × 9
Multiply all: 7×5=35; 4×6=24; 3×9=27
Left to right: 35 – 24 = 11; 11 + 27 = 38

19) 7 × 4 ÷ 2 + 5 × 3
Left to right for × and ÷: 7×4=28; 28÷2=14
Then 5×3=15
Add: 14 + 15 = 29

20) (5² – 7) ÷ (4² + 2)
Exponents: 5²=25; 4²=16
Parentheses: 25–7=18; 16+2=18
Divide: 18 ÷ 18 = 1
