→ Then multiply left to right: 4×3=12, 12×5=
60 → Answer:
C
13) 12 – (3 + 4 × 2)
→ Inside parentheses: do multiplication first: 4×2=8, then 3+8=11
→ Then subtract: 12–11=
1 → Answer:
A
14) (7 + 3) × (12 – 5)
→ Both parentheses: 7+3=10, 12–5=7
→ Then multiply: 10×7=
70 → Answer:
B
15) 18 + 12 ÷ (15 – 11)
→ Parentheses first: 15–11=4
