Use each number exactly once. You may use +, −, ×, ÷ and parentheses. Fractions and negative intermediate results are allowed. You cannot join digits or use powers.
A small hint
Try doing a small calculation inside parentheses first.
One possible solution
(9-6)×2×3 = 18
- 9 − 6 = 3
- 3 × 2 = 6
- 6 × 3 = 18
Read the solution
