Order of Operations Worksheets | Order of Operations Easy or Hard - Free Printable

Let's solve each problem step by step using the order of operations, often remembered by the acronym PEMDAS:

- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)

1. $ 3 - (2^3 \div 1) + 5 $

- $ 2^3 = 8 $
- $ 8 \div 1 = 8 $
- $ 3 - 8 + 5 = -5 + 5 = 0 $

✔ Answer: 0

---

2. $ (6^3 - 9 - 1) $

- $ 6^3 = 216 $
- $ 216 - 9 = 207 $
- $ 207 - 1 = 206 $

✔ Answer: 206

3. $ (5 + 7^3) \div 7 \times 7 $

- $ 7^3 = 343 $
- $ 5 + 343 = 348 $
- $ 348 \div 7 = 49.714... $ → Wait! But we should do this carefully.

Wait — order matters:
$ 348 \div 7 = 49.714... $? Actually, let’s compute exactly:

But hold on — it's $ 348 \div 7 \times 7 $

Division and multiplication go left to right:
- $ 348 \div 7 = 49.714... $? No, better to keep as fraction or check if divisible.

Wait: $ 348 \div 7 = 49.714... $? Let's divide:
7 × 49 = 343 → remainder 5 → so $ 348 \div 7 = 49\frac{5}{7} $

Then $ 49\frac{5}{7} \times 7 = 348 $

Alternatively, notice:
$ (5 + 7^3) \div 7 \times 7 = (5 + 343) \times \frac{1}{7} \times 7 = 348 \times 1 = 348 $

Because dividing by 7 then multiplying by 7 cancels out.

✔ Answer: 348

4. $ (2 - 7) - 8 - 3 $

- $ 2 - 7 = -5 $
- $ -5 - 8 = -13 $
- $ -13 - 3 = -16 $

✔ Answer: -16

5. $ (6 + 7^2) + 1 $

- $ 7^2 = 49 $
- $ 6 + 49 = 55 $
- $ 55 + 1 = 56 $

✔ Answer: 56

6. $ 4^3 - (2 + 2^3) \times 5 $

- $ 4^3 = 64 $
- $ 2^3 = 8 $
- $ 2 + 8 = 10 $
- $ 10 \times 5 = 50 $
- $ 64 - 50 = 14 $

✔ Answer: 14

7. $ (6 - 1 + 7) $

- $ 6 - 1 = 5 $
- $ 5 + 7 = 12 $

✔ Answer: 12

8. $ (3^2 - 3^2) + 5 $

- $ 3^2 = 9 $
- $ 9 - 9 = 0 $
- $ 0 + 5 = 5 $

✔ Answer: 5

---

9. $ (7 + 8 - 4^2) \times 2 + 1 $

- $ 4^2 = 16 $
- $ 7 + 8 = 15 $
- $ 15 - 16 = -1 $
- $ -1 \times 2 = -2 $
- $ -2 + 1 = -1 $

✔ Answer: -1

---

10. $ 6 - (8 + 3^3) - 4 $

- $ 3^3 = 27 $
- $ 8 + 27 = 35 $
- $ 6 - 35 = -29 $
- $ -29 - 4 = -33 $

✔ Answer: -33

11. $ (3 + 3 \times 6 + 3^2 - 3) $

- Exponents: $ 3^2 = 9 $
- Multiplication: $ 3 \times 6 = 18 $
- Now: $ 3 + 18 + 9 - 3 $
- Left to right: $ 3 + 18 = 21 $, $ 21 + 9 = 30 $, $ 30 - 3 = 27 $

✔ Answer: 27

---

12. $ (7 + 2^3) \times 9 $

- $ 2^3 = 8 $
- $ 7 + 8 = 15 $
- $ 15 \times 9 = 135 $

✔ Answer: 135

---

13. $ (3 \times 6) - 5 $

- $ 3 \times 6 = 18 $
- $ 18 - 5 = 13 $

✔ Answer: 13

---

14. $ 6 \times (2 \div 1) \div 1 $

- $ 2 \div 1 = 2 $
- $ 6 \times 2 = 12 $
- $ 12 \div 1 = 12 $

✔ Answer: 12

---

15. $ (2^3 - 9 - 8) \div 3 \times 3 $

- $ 2^3 = 8 $
- $ 8 - 9 = -1 $
- $ -1 - 8 = -9 $
- $ -9 \div 3 = -3 $
- $ -3 \times 3 = -9 $

✔ Answer: -9

---

16. $ 2^3 \div (7 \div 7 \div 8) $

- $ 2^3 = 8 $
- Inside parentheses: $ 7 \div 7 = 1 $, $ 1 \div 8 = 0.125 $
- So: $ 8 \div 0.125 = 64 $

(Or: $ 8 \div \frac{1}{8} = 8 \times 8 = 64 $)

✔ Answer: 64

17. $ (6 + 6^2) \times 3 $

- $ 6^2 = 36 $
- $ 6 + 36 = 42 $
- $ 42 \times 3 = 126 $

✔ Answer: 126

---

18. $ (3 + 1) \times 8 \times 4 $

- $ 3 + 1 = 4 $
- $ 4 \times 8 = 32 $
- $ 32 \times 4 = 128 $

✔ Answer: 128

19. $ (7^3 \times 4) + 7 $

- $ 7^3 = 343 $
- $ 343 \times 4 = 1372 $
- $ 1372 + 7 = 1379 $

✔ Answer: 1379

20. $ 6^2 - 3 \times (3^2 \times 2) + 5 $

- $ 6^2 = 36 $
- $ 3^2 = 9 $
- $ 9 \times 2 = 18 $
- $ 3 \times 18 = 54 $
- $ 36 - 54 = -18 $
- $ -18 + 5 = -13 $

✔ Answer: -13
