Sum across the secondary diagonal: 4 + 5 + 10 = 19. Difference: 4 - 19 = 15. Now the last step is to find the difference between the sum of diagonals, so add the first diagonal and the second diagonal after that mod the difference so 4 - 19 = 15. Hence we got our solution. Note: x is the absolute value of x. sharon landers md
