In recreational mathematics, a magic square of order n is an arrangement of n² numbers, usually distinct integers, in a square, such that the n numbers in all rows, all columns, and both diagonals sum to the same constant. A normal magic square contains the integers from 1 to n². The term "magic square" is also sometimes used to refer to any of various types of word square. Normal magic squares exist for all orders n ≥ 1 except n = 2, although the case n = 1 is trivial—it consists of a single cell containing the number 1. The smallest nontrivial case, shown below, is of order 3. The constant sum in every row, column and diagonal is called the magic constant or magic sum, M. The magic constant of a normal magic square depends only on n and has the value For normal magic squares of order n = 3, 4, 5, …, the magic constants are: At Macworld Expo 2009, Apple Inc. cofounder Steve Wozniak created a magic square after asking his audience to suggest a random number for the magic constant.From Wikipedia under the

Q. Sorry, I mean make. (-: Asked by Tropical - Sat Nov 24 08:07:13 2007 - - 5 Answers - 0 Comments A. Consider the 3x3 square, which has the numbers 1-9. These numbers sum to 45, so each row, column and diagonal must sum to 45/3 = 15. Also there are 8 combinations of 15 we need (3 rows, 3 columns, 2 diagonals). Let's list the combinations that add up to 15. 1) 4,5,6 2) 3,5,7 3) 2,5,8 4) 1,5,9 5) 1,6,8 6) 2,6,7 7) 2,4,9 8) 3,4,8 You'll see that the only number that features four times is the 5. So the 5 goes in the center. The 2,4,6,8 each feature 3 times, so they must go in the diagonals. The 1,3,7,9 feature 2 times each, so they go in the last 4 spaces. Now just rearrange them so include all 8 combinations. 2,7,9 9,5,1 4,3,8 Answered by Dr D - Sat Nov 24 08:54:22 2007 From Yahoo Answer Search: "Magic Square" See also:
