A magic square is a group of numbers arranged in a certain way so that the numbers have an interesting property – that is, the sum of any row, column, or diagonal is the same.

Historians believe the first magic square called lo-shu dates from Ancient China before 2000 B.C. There is a legend about its discovery that says an emperor saw the special number sequence on the shell of a tortoise near the bank of the Yellow River.
