Make 24

How to play

Four numbers are shown. Combine them using +, −, ×, ÷ to make 24. Tap a number, pick an operator, tap another number — the result replaces both. Repeat until one number remains. Every number must be used exactly once. At higher levels fractions (½, ⅓, ¼) appear among the starting numbers.

Examples

1, 1, 4, 6  →  1 × 1 × 4 × 6 = 24
2, 3, 5, 9  →  (5 − 2) × 9 − 3 = 24
