Bodmas Worksheet with 20 math problems and answer columns.

To solve the problems in the BODMAS worksheet, we need to follow the order of operations as specified by the BODMAS rule:

BODMAS Rule:
1. Brackets
2. Orders (powers and roots, etc.)
3. Division and Multiplication (left-to-right)
4. Addition and Subtraction (left-to-right)

Let's solve each problem step by step.

---

Problem 1: \( 7 - (-5) \)

- Subtracting a negative is the same as adding.
- \( 7 - (-5) = 7 + 5 = 12 \)

Answer: \( 12 \)

---

Problem 2: \( 32 - 3 \times 15 \)

- First, perform multiplication: \( 3 \times 15 = 45 \).
- Then, subtract: \( 32 - 45 = -13 \).

Answer: \( -13 \)

---

Problem 3: \( 9 \div 3 - 7 \)

- First, perform division: \( 9 \div 3 = 3 \).
- Then, subtract: \( 3 - 7 = -4 \).

Answer: \( -4 \)

---

Problem 4: \( (10 + 6) \div 4 - 4 \)

- First, solve the brackets: \( 10 + 6 = 16 \).
- Next, divide: \( 16 \div 4 = 4 \).
- Finally, subtract: \( 4 - 4 = 0 \).

Answer: \( 0 \)

---

Problem 5: \( 8 \times (5 - 3) \)

- First, solve the brackets: \( 5 - 3 = 2 \).
- Then, multiply: \( 8 \times 2 = 16 \).

Answer: \( 16 \)

---

Problem 6: \( -15 + 20 \)

- Simply add: \( -15 + 20 = 5 \).

Answer: \( 5 \)

---

Problem 7: \( 4 \times 2 \times 3 \)

- Perform multiplication from left to right: \( 4 \times 2 = 8 \), then \( 8 \times 3 = 24 \).

Answer: \( 24 \)

---

Problem 8: \( 5 + (8 - 5) \)

- First, solve the brackets: \( 8 - 5 = 3 \).
- Then, add: \( 5 + 3 = 8 \).

Answer: \( 8 \)

---

Problem 9: \( (6 + 4) \div (5 \times 2) \)

- Solve the brackets:
- \( 6 + 4 = 10 \)
- \( 5 \times 2 = 10 \)
- Divide: \( 10 \div 10 = 1 \).

Answer: \( 1 \)

---

Problem 10: \( 42 \div 3 - 12 \)

- First, divide: \( 42 \div 3 = 14 \).
- Then, subtract: \( 14 - 12 = 2 \).

Answer: \( 2 \)

---

Problem 11: \( (11 + 5) \div 4 + (-4) \)

- Solve the brackets: \( 11 + 5 = 16 \).
- Divide: \( 16 \div 4 = 4 \).
- Add: \( 4 + (-4) = 0 \).

Answer: \( 0 \)

---

Problem 12: \( -1 - (-26) \)

- Subtracting a negative is the same as adding.
- \( -1 - (-26) = -1 + 26 = 25 \).

Answer: \( 25 \)

---

Problem 13: \( (12 + 7) - (2 - 23) \)

- Solve the brackets:
- \( 12 + 7 = 19 \)
- \( 2 - 23 = -21 \)
- Subtract: \( 19 - (-21) = 19 + 21 = 40 \).

Answer: \( 40 \)

---

Problem 14: \( 20 - 2 \times 11 \)

- First, multiply: \( 2 \times 11 = 22 \).
- Then, subtract: \( 20 - 22 = -2 \).

Answer: \( -2 \)

---

Problem 15: \( 8 \times 5 + (4 - 14) \)

- Solve the brackets: \( 4 - 14 = -10 \).
- Multiply: \( 8 \times 5 = 40 \).
- Add: \( 40 + (-10) = 40 - 10 = 30 \).

Answer: \( 30 \)

---

Problem 16: \( 25 - (-37) \)

- Subtracting a negative is the same as adding.
- \( 25 - (-37) = 25 + 37 = 62 \).

Answer: \( 62 \)

---

Problem 17: \( 6 - (-10) \)

- Subtracting a negative is the same as adding.
- \( 6 - (-10) = 6 + 10 = 16 \).

Answer: \( 16 \)

---

Problem 18: \( 24 \div (-2) - (-4) \times 11 \)

- First, divide: \( 24 \div (-2) = -12 \).
- Next, multiply: \( (-4) \times 11 = -44 \).
- Subtract: \( -12 - (-44) = -12 + 44 = 32 \).

Answer: \( 32 \)

---

Problem 19: \( (10 - 17) - (25 - 15) \)

- Solve the brackets:
- \( 10 - 17 = -7 \)
- \( 25 - 15 = 10 \)
- Subtract: \( -7 - 10 = -17 \).

Answer: \( -17 \)
