In Mathematics we study the nature of numbers and magic squares are a perfect example to show their natural symmetryHistory is Very ImportantThere is evidence to date magic squares as early as the 6th century due to Chinese mathematiciansHistory is Very ImportantThere is evidence to date magic squares as early as the 6th century due to Chinese mathematiciansIt was later discovered by the Arabs in the 7th centuryHistory is Very ImportantThere is evidence to date magic squares as early as the 6th century due to Chinese mathematiciansIt was later discovered by the Arabs in the 7th centuryThe Lo Shu square is the first recorded magic square

History is Very ImportantThere is evidence to date magic squares as early as the 6th century due to Chinese mathematiciansIt was later discovered by the Arabs in the 7th centuryThe Lo Shu square is the first recorded magic square
The sum in each row, column, diagonal is 15 which is the number of days in each of the 24 cycles of the Chinese solar year

It went as far as being attributed mythical properties. (Thank you Wikipedia for great information)

Bimagic SquareA Bimagic Square is a magic square that is also a magic square if all of its numbers are squaredBimagic SquareA Bimagic Square is a magic square that is also a magic square if all of its numbers are squaredThe first known bimagic square is of order 8Bimagic SquareA Bimagic Square is a magic square that is also a magic square if all of its numbers are squaredThe first known bimagic square is of order 8It has been shown that all 3 by 3 bimagic squares are trivialBimagic Square
Multiplication Magic SquareA square which is magic under multiplication is called a multiplication magic square. The magic constants increase very fast with the order of the square.Multiplication Magic SquareA square which is magic under multiplication is called a multiplication magic square. The magic constants increase very fast with the order of the square.For orders 3 and 4 the following are the smallest multiplication magic squares
Word SquareA set of words having the same number of letters; when the words are written in a square grid horizontally, the same set of words can be read vertically Word SquareA set of words having the same number of letters; when the words are written in a square grid horizontally, the same set of words can be read vertically Because we speak English we are naturally interested in the ones made of English wordsWord SquareA set of words having the same number of letters; when the words are written in a square grid horizontally, the same set of words can be read vertically Because we speak English we are naturally interested in the ones made of English wordsThere are word squares of order 3 through 9 (cases 3, 4, 9 are displayed below)

The hunt for a word square of order 10 is still going and apparently it has been called the holy grail of logology.Fibonacci Magic SquareThe presentation would not be complete with a reference to the Fibonacci numbersFibonacci Magic SquareThe presentation would not be complete with a reference to the Fibonacci numbersStart with the basic 3 by 3 magic square

Even though this is not a magic square it so happens that the sum of the products of the three rows is equal to the sum of the products of the three columns.
