I am a student at Marquette University who enjoys a math puzzle every once in awhile. I came across one that is giving me some trouble, and was wondering if you could offer some help. The question asks:

Place the numbers 1-16 in the cells of the following magic square so that the sum of each row, column, and diagonal is the same

X 2 X X 5 X X 8 X 7 6 X X X 15 1

Besides using the "quess and check" approach, is there an algorithm to solve this sort of problem. I would greatly appreciate your expertise.

Thank you
