A magic square is a set arrangement of numbers, usually whole numbers, in a square grid, where each row, column and diagonal adds up to the same value, called 'magic number'.
Magic squares are known from ancient times. Arab mathematicians already knew them as early as the 7th century. They may have learned about them from the Indian culture or perhaps from China.
Magic squares have also been used by different artists over the last centuries, sometimes with allegorical meaning.
Magic squares can contain fractions, like these examples. Try to fill them up. It will be easier if you express all the fractions with a common denominator!
