Home / Make 24 solver
Make 24 with your four numbers.
Enter four numbers to find ways to make 24 using addition, subtraction, multiplication and division. Each number is used exactly once. Open any answer for worked steps, including exact fractions, or choose another target from 1 to 100.
How to use the make 24 calculator
Type your four numbers, leave the target at 24, and select Find solutions. Each answer uses all four inputs once. Repeated values are separate numbers: 3, 3, 8, 8 uses both threes and both eights.
Why some answers use fractions
For 3, 3, 8, 8, try 8 ÷ (3 − 8 ÷ 3). First 8 ÷ 3 = 8/3, then 3 − 8/3 = 1/3, and finally 8 ÷ (1/3) = 24. The solver keeps these fractions exact.
Can every four-number puzzle make 24?
No. Some combinations have no solution with these four operations. Try 1, 1, 1, 1: even multiplying two sums only makes 4. Our playable puzzles are checked before they are dealt.
Choose another target
The same calculator can make 36, 48, 100 or any whole-number target from 1 to 100. Inputs may be whole numbers from −99 to 99. It uses +, −, ×, ÷ and parentheses, without factorials, roots or joining digits. For those extra operations, try Four Fours.
Up to 200 distinct expressions are returned. Equivalent rearrangements may still appear; the count is not a count of fundamentally different mathematical methods.
Bigger number puzzles
Got six numbers instead of four? The Countdown numbers solver takes six numbers and a target from 100 to 999 and shows the worked steps, or the closest result when the exact target is out of reach. For a classic challenge with a single digit, try Four Fours: make every number from 1 to 50 with exactly four 4s.
