Let’s work through each problem one by one. We’ll follow the order of operations:
Parentheses → Exponents → Multiplication and Division (left to right) → Addition and Subtraction (left to right)
We’ll calculate each expression and match it to A, B, or C.

---

1) 14 – 2 × 5
→ Multiply first: 2 × 5 = 10
→ Then subtract: 14 – 10 = 4 → A

2) 3 × 4 – 2 × 5
→ Multiply left to right: 3×4=12, 2×5=10
→ Subtract: 12 – 10 = 2 → B

3) 2 + 3 × 4 + 5
→ Multiply first: 3×4=12
→ Add left to right: 2+12=14, 14+5=19 → B

4) 24 – 7 × 3 + 1
→ Multiply: 7×3=21
→ Subtract and add left to right: 24–21=3, 3+1=4 → A

5) 20 ÷ 2 + 3
→ Divide first: 20÷2=10
→ Add: 10+3=13 → C

6) 15 + 4 × 10 – 5
→ Multiply: 4×10=40
→ Add/subtract left to right: 15+40=55, 55–5=50 → B

7) 10 – 7 + 3 × 2
→ Multiply: 3×2=6
→ Add/subtract left to right: 10–7=3, 3+6=9 → A

8) 2 + 9 ÷ 3 + 6
→ Divide: 9÷3=3
→ Add left to right: 2+3=5, 5+6=11 → C

9) 20 – 3 × 4 ÷ 2
→ Multiply and divide left to right: 3×4=12, 12÷2=6
→ Subtract: 20–6=14 → A

10) 30 ÷ 5 × 3 + 6
→ Divide and multiply left to right: 30÷5=6, 6×3=18
→ Add: 18+6=24 → C

11) 3 × (9 – 5) + 6
→ Parentheses first: 9–5=4
→ Multiply: 3×4=12
→ Add: 12+6=18 → B

12) 4 × (6 – 3) × 5
→ Parentheses: 6–3=3
→ Multiply left to right: 4×3=12, 12×5=60 → C

13) 12 – (3 + 4 × 2)
→ Inside parentheses: multiply first → 4×2=8, then 3+8=11
→ Subtract: 12–11=1 → A

14) (7 + 3) × (12 – 5)
→ Both parentheses: 7+3=10, 12–5=7
→ Multiply: 10×7=70 → B

15) 18 + 12 ÷ (15 – 11)
→ Parentheses: 15–11=4
→ Divide: 12÷4=3
→ Add: 18+3=21 → A

16) ½ × (4 + 5 – 3)
→ Parentheses: 4+5=9, 9–3=6
→ Multiply: ½ × 6 = 3 → B

17) 4 × 5 – 12 ÷ 2
→ Multiply and divide left to right: 4×5=20, 12÷2=6
→ Subtract: 20–6=14 → C

18) 8 + 20 ÷ 4 + 6
→ Divide: 20÷4=5
→ Add left to right: 8+5=13, 13+6=19 → C

19) 3 × (12 – 5 × 2)
→ Inside parentheses: multiply first → 5×2=10, then 12–10=2
→ Multiply: 3×2=6 → A

20) (30 – 12) ÷ (9 – 3)
→ Both parentheses: 30–12=18, 9–3=6
→ Divide: 18÷6=3 → B
