Magic squares are mathematical puzzles where integers are arranged in a square grid so that the sums of each row, column and diagonal are equal. For example, in a 3x3 magic square, the center number is first placed, then numbers are added and subtracted diagonally and vertically to fill in the rest of the spaces so that each row, column and diagonal adds up to the same number. Magic squares have entertained people while exercising their minds for many years through this mathematical contrivance.

3. The magic squares for many years are a
mathematical contrivance that entertains people
while practicing their minds! As proved by the
word, it is a square tables are positioned integers
in such a way so as horizontal, vertical and
diagonal their sum is the same and each number
cannot appear twice. The sum of each magic square
called otherwise:
«Magical element»

4. Example how do magic squares
In the center put a number e.g. 5:
_ _ _
_ 5 _
_ _ _

5. Diagonal add and subtract the same number:
B.C. 2, so we get the numbers 7 and 3 respectively and place
them diagonally:
7 _ _
_ 5 _
_ _ 3
We find that sum to 15

6. At the same way add and subtract another number, for
example 1, so we get the numbers 6 and 4:
7 _ 6
_ 5 _
4 _ 3

7. Finally, make the boxes we were left with the numbers
which complement the sum (15).
