This precalculus video tutorial provides a basic introduction into multiplying matrices. Learn how to do it with this article. By multiplying the first row of matrix a by each column of matrix b, we get to row 1 of resultant matrix ab.

When You Multiply A Matrix Of 'M' X 'K' By 'K' X 'N' Size You'll Get A New One Of 'M' X 'N' Dimension.

Before you attempt to multiply matrices, make sure that the second matrix you want to multiply has the same number of rows as the number of columns of the first matrix. Next, multiply the elements of the i th row of the first matrix by the elements of the j th column in the second matrix. Multiplying matrices can be performed using the following steps:
