The preceding chapter discussed scalar multiplication with vectors. Remember, a vector is just a single row or single-column matrix, so scalar multiplication works the same way with matrices as it does with vectors.

At one point, there was a suggestion that rather than subtracting corresponding entries, you might want to add the negative of the second matrix. Flipping the sign of each entry is the same as multiplying the matrix by –1.
