So we have to be very careful about multiplying matrices. Sentences like "multiply the two matrices A and B" do not make sense. You must know which of the two matrices will be to the right (of your multiplication) and which one will be to the left;

Addition of Matrices: In order to add two matrices, we add the entries one by one. Note: Matrices involved in the addition operation must have the same size. ... What about multiplying two matrices? Such operation exists but the calculations involved are complicated. On the next page, we will discuss matrix multiplication.

Therefore, a 2x5 matrix would have two rows and five columns. When multiplying matrices, first you need to make sure that the dimension of the columns (vertical) in the first matrix is ... If they are not the same, then the two matrices cannot be multiplied. For this lesson, we will focus on multiplying with two matrices.
