Multiplication Just like adding and subtracting we first need to take a look at the size of the two matrices we want to multiply Matrix A Matrix B The number of columns in the first matrix MUST be the same as the number of rows in the second matrix otherwise the answer is “undefined”
What is a solution using matrix multiplication?
Solution using matrix multiplication ?We represent the number of each model sold using a row matrix (4X1) and we use a 1X4 column matrix to represent the sales price of each model. When a 4X1 matrix is multiplied by a 1X4 matrix, the result is a 1X1 matrix of a single number.
