where each row, column and diagonal sums to 15. Now replace the number 1 by the magic square we just started with, replace the number 2 by 2 times the 3 x 3 magic square we just started with, replace the number 3 by 3 times the 3 x 3 magic square we just started with all the way up to replacing the number 9 by 9 times the 3 x 3 magic square we started with. This completes the solution of your problem (I'm curious - which math class are you taking that gave you this problem?)

To mention there's another type of magic square (nested magic square) where peeling off each border leaves you with another magic square.
