## Magic Quadrant in the cultures of the world

An example of the magic square is the Luo Shu, which is a table of 3 to 3. It entered the numbers from 1 to 9 so that the sum of each row and diagonal gives the number 15.

## How to solve the square with an even number of cells

You will need a piece of paper with a painted on them 4x4 square, a pencil and an eraser.

Fill in the cells of the square numbers from 1 to 16 starting from the top left cell.

1; 2; 3; 4

5; 6; 7; 8

9; 10; 11; 12

13; 14; 15; 16

The magic constant of the square - 34. Swap the numbers on the diagonal line from 1 to 16. For simplicity interchange 16 and 1, and then 6, and 11. The result will be the diagonal numerals 16, 11, 6, 1.

16; 2; 3; 4

5, 11; 7; 8

9, 10; 6; 12

13; 14; 15; 1

Swap of the second diagonalline. This line begins with the digits 4 and ends with the numeral 13. The swap them. Now reverse the two other numbers - 7 and 10. From top to bottom on the line number will be placed in the following order: 13, 10, 7, 4.

16; 2; 3, 13

5; 11; 10; 8

9; 7; 6; 12

4; 14; 15; 1

If you consider the amount per line, you get 34. This method works with other squares with an even number of cells.
