If ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’, and ‘÷’ means ‘+’, find the value of: 12 + 6 − 3 × 4 ÷ 2.

1. 7
2. 8.5
3. 9.5
4. 10

Correct answer: 9.5

Solution

Substitute the symbols: 12 + 6 − 3 × 4 ÷ 2 becomes 12 − 6 × 3 ÷ 4 + 2. Now apply BODMAS: 6 × 3 ÷ 4 = 4.5, so the expression is 12 − 4.5 + 2 = 9.5.
