The 24 Game

• tests one's mental arithmetic.

How it works:

• You are randomly given four digits, each from one to nine, with repetitions allowed.
• The goal is to enter an expression that evaluates to 24

Tips:

• Only multiplication, division, addition, and subtraction operators/functions are allowed.
• Division should use floating point or rational arithmetic, etc, to preserve remainders.
