Question 893055
<pre>
By a computer program, I did an exhaustive search of all
possibilities.  The computer program showed that there is 
no way to get exactly 24 by adding, subtracting, multiplying 
and dividing those four number.  The closest the computer 
found was:

1/3+4x6 = 24.333333333 which rounds to 24.
