Calculating 24

The rule is simple: pick any four cards and try to get a result of 24 from the numbers on the cards, using only the four basic arithmetic operations: addition (+), subtraction (-), multiplication (*), and division (/).

Jack (J), Queen (Q), King (K), and Ace (A) represent 11, 12, 13, and 1 respectively.

For example, given numbers 2, 3, 5 and 8, we can get such an expression:

This Demonstration tries to find all distinct answers for four given cards.
