=**Magic Squares **=

==A 'normal' magic square is a square that when arranged in an //n//x//n// manner with integers from 1-//n//^2, all the columns, rows, and main diagonals add up to the same sum. To find out what the sum is, you can use the formula //n//(//n//^2+1)/2. One you have a complete magic square, if you subtract each number from //n//^2-1, you get what's called a complementary magic square. There are also magic squares where, when multiplied, the rows/columns/main diagonals have the same product. These are called multiplication magic sqaures.==

Here's a normal 3x3 magic square:

Where it came from:
==Legend says that in ancient China, there was a huge flood. The people were trying to makes sacrifices to one of the river gods, 'Lo', to calm him. Every time they gave a sacrifice, a turtle came out and walked around it. It didn't accept the sacrifice until one time, a child noticed the magic square number pattern on the back of the turtle's shell. That's when they realized the number of sacrifices was supposed to 15.==
