Worked Solution

Step 1: Evaluate the bracket first (BODMAS — Brackets first). (8 − 6) = 2. The expression becomes: 36 + 24 ÷ 2 × 5 − 18. Step 2: Division and multiplication, left to right. 24 ÷ 2 = 12, then 12 × 5 = 60. The expression becomes: 36 + 60 − 18. Step 3: Addition and subtraction, left to right. 36 + 60 = 96, then 96 − 18 = 78. Answer: 78

Correct answer: 78
