Stuck? Work backwards from 24.

Instead of trying random operations, look for useful shapes.

Look for factors of 24

24 is 3 × 8, 4 × 6, 2 × 12 and 1 × 24. Ask whether your four numbers can be turned into one of those pairs.

Make a useful intermediate number

A pair that becomes 2, 3, 4, 6, 8 or 12 is often worth exploring because those numbers fit 24 naturally.

Subtraction can unlock the puzzle

If two numbers are close together, their difference may give you the small factor you need.

Keep the rules in view

Every number must be used exactly once, and division must result in a whole number.
