Construction Of A Magic Square?

A magic square is an NxN matrix where every row, column, and diagonal add up to the same number. To construct a perfect magic square, follow these steps:

1. Copy one of the squares from here and you are done.
2. Use a magic square calculator to create any size, such as 3×3 or 5×5, by choosing the size of the square.
3. Construct a magic square of even order by reversing the order of the rightmost n/2 columns and the order of the bottom n/2 rows. Divide the square into 2×2 subsquares.
4. To create a new magic square, draw a 4×4 blank grid and choose a two-digit number higher than 20 or ask your volunteer to select it.
5. List the nine consecutive numbers in order and add them up then divide by three. The very middle number in a consecutive number list is the number for the middle.
6. A magic square is an N×N grid of numbers in which the entries in each row, column, and main diagonal sum to the same number (equal to N(N2+1)/2).
