Number Solver

Use the numbers on the four red cards and the four operations of arithmetic (addition, subtraction, multiplication and division) to make the number 24.

You can add, subtract, multiply and divide the four numbers in any order to reach 24. Click any number, then an operator, and then another number to perform one calculation. The number you selected will remain highlighted, so you can select another operation and another number, or you can click a different number to start a new operation with that number.

You need to use all four cards to make 24 and earn the gold card. There are no limits on the number of operations you must use.

Stumped? Use the white flag icon at the top left to surrender and see one possible way to make 24 with these cards. But be warned: when you surrender, you'll lose all of your accumulated gold cards!
