This Java applet allows you to type in 4 integers and then find all solutions to the 24 Game.

The rules for the 24 Game are that you must find an arithmetic combination that uses each of the four numbers exactly once (and no other numbers) as well as the basic arithmetic operations of addition, subtraction, multiplication, and division.

Just type in the four numbers in the text boxes and then push the Compute button. The results will appear in the text area below.
