To add these, you just add the corresponding components
first row, first column: -8 + (-2) = -10 ------------------------------------------------------- first row, second column: -1 + 0 = -1 ------------------------------------------------------- first row, third column: 7 + (-2) = 5 ------------------------------------------------------- etc etc
