Magic square

In recreational mathematics, a magic square is an arrangement of numbers in a square grid, where the numbers in each row, and in each column, and the numbers in the forward and backward main diagonals, all add up to the same number. A magic square has the same number of rows as it has columns, and in conventional math notation, "n" stands for the number of rows it has. Thus, a magic square always contains n2 numbers, and its size is described as being "of order n". A magic square that contains the integers from 1 to n2 is called a normal magic square.
