Question
Find the sum and the difference of the matrices.$$ \left[\begin{array}{rrr} 1 & 8 & -2 \\ -4 & -5 & 6 \end{array}\right],\left[\begin{array}{rrr} -1 & 9 & 2 \\ 3 & 3 & -5 \end{array}\right] $$
Step 1
This means we add the first element of the first matrix to the first element of the second matrix, the second element of the first matrix to the second element of the second matrix, and so on. This gives us the sum of the two matrices. Show more…
