Multiplication of two matrices
i. Multiplication is only possible if the first matrix has the similar number of columns as the second matrix has rows. If A is the order a×b, then B has to be of the order b×c. If the A×B = D, then D must be of the order a×c.
ii. The general method of multiplication is which the elements in row m of the first matrix are multiplied by the corresponding elements in columns n of the second matrix and the products acquired are then added providing a single number.
