Super - Crazy Math SquaresMath brain teasers require computations to solve.
Place 16 different 2-digit numbers in a 4x4 square grid so that they add up to the same number horizontally, vertically, and diagonally, and horizontally, vertically, and diagonally when turned UPSIDE - DOWN.
HintThis is not a trick question.
The magic sum is 264.
AnswerThe numbers should be like this:
96 11 89 68
88 69 91 16
61 86 18 99
19 98 66 81
*Note that the only numbers used are 1, 6, 8, and 9, because these numbers can be read as either the same or a different number when turned upside down.
Example: 1 and 8 look the same upside down, but 6 turns into 9 and 9 turns into 6.
So 89 becomes 68, 99 becomes 66, etc., and the numbers in the box still add up to 264 (vertically, horizontally, and diagonally) upside down!!
