Add the diagonal totals up
Start at the bottom rightMove to the top left
6 = 6
8 + 2 + 3 = 13
Since our sum is greater than 10, we need to carry a 1 for the next sum of diagonals
This entry becomes 3
4 + 6 + 4 + 8 + 4 + 1 = 27
Since our sum is greater than 10, we need to carry a 2 for the next sum of diagonals
This entry becomes 7
3 + 5 + 4 + 5 + 4 + 2 = 23
Since our sum is greater than 10, we need to carry a 2 for the next sum of diagonals
This entry becomes 3
2 + 6 + 6 + 2 = 16
Since our sum is greater than 10, we need to carry a 1 for the next sum of diagonals
This entry becomes 6
7 + 1 = 8
