# Window Sum

Directions: Using the digits 0-9, no more than once, complete the puzzle so that the sum of each side is equivalent.

### Hint

The sum of the middle numbers on opposite sides are always the same

There are multiple answers, for example, you can arrange the numbers, 0, 1, 2, 3, 4, 5, 6, 7 in such a way that the sum of each side equals 9. Another solution includes using 0,5,7,3,2,6,4,8 and have sums of 12.
