193 known as the magic constant M_2n1nsum_k1n2k12nn21. So for the 4 by 4 magic square each row each column and both diagonals would sum to 4 4 1 2 34. ConstantSum nn 2 12 Where n is number of rows or columns in the square.
We will easily find out that square constant by using following formula. Remember the equation. The constant sum in every row column and diagonal are called the magic constant or magic sum M.
Either choice produces a pan-magic square. For example if n 3 Constant 33 2 12 3 X 5 15. Now flip the numbers in the diagonals the red lines.

The integer portion becomes the starting. In the Magic Square for 34 arrange the numbers in numerical order and take every other cell starting with the lowest. We shall denote by Hnpsqthe number of n n magic squares of sum s.
It will be the principal aim of these notes to study the properties of the functions Hnand derive explicit formul for low values of n. All you have to do is. To determine the sum of any normal magic square we use the formula.
The number 15 is called the magic number of the 3x3 square. Yes there are magic cubes their magic value is M nn312 M n n 3 1 2 which may or may not have magic diagonals. Here is a simple easy to remember way to make a 4 by 4 magic square.

This corresponds to the following equation. To determine the sum of any normal magic square we use the formula. Many people have found these.
In the image below Ray identified the cells that contain 1 3 5 and 7. The magic constant of a normal magic square depends only on n and has the following value.
