Think! What if the magic square had an even number of cells. There's your answer.
[ 9 ] [ 2 ] [ 7 ][ 4 ] [ 6 ] [ 8 ][ 5 ] [10 ] [ 3 ]
Take any valid 4 x 4 magic square. For example: 9 6 3 16 4 15 10 5 14 1 8 11 7 1 10 16 Decrease every number by 6, so that the smallest number you will find in the square is -5, and the largest number in the square will be 10. This is a valid magic square for the set of numbers given and can be rotated any of four ways, and reflected either of two ways.
all sides of a square are the same length. Only opposite sides of a rectangle have equal length, adjacent sides do not.
A magic square is a square full of numbers so that all rows and columns, and both diagonals, add up to the same number. For example: 2 7 6 9 5 1 4 3 8 Every row, every column and both the diagonals add up to 15.
