Mathematical expressions with BODMAS order

📚 Part 1: Understanding BODMAS

1. What does each letter in BODMAS stand for? Fill in the blanks:

B = ________________

O = ________________

D = ________________

M = ________________

A = ________________

S = ________________

2. Circle the operation you would perform FIRST in each expression:

a) 8 + 3 × 5 → Operations: + or ×

b) (12 ÷ 4) + 2² → Operations: ÷ or + or ²

c) 15 - 6 ÷ 2 → Operations: - or ÷

3. Which expression equals 14?

2 + 3 × 4

(2 + 3) × 4

2 × 3 + 4

2 × (3 + 4)

✏️ Part 2: Step-by-Step Calculations

4. Calculate 8 + (3 × 5). Show each step clearly:

5. Calculate (12 ÷ 4) + 2². Show each step clearly:

6. Calculate 7 + 3 × (10 - 6) - 4. Show each step clearly:

7. Calculate (3² + 4) × 2 - 5. Show each step clearly:

🌟 Part 3: Real-World Problems

8. A jacket costs $45. It is on sale for 20% off, plus there's an additional $5 rebate. Write an expression to calculate the final price, then solve it:
