This precalculus video tutorial provides a basic introduction into multiplying matrices. It explains how to tell if you can multiply two matrices together and how to determine the order of the new matrix. The order of the new matrix is based on the rows of the first matrix and the number of columns in the second matrix. To multiply two matrices together, multiply the rows of the first matrix by the columns of the second matrix and find the sum of the products. This video contains plenty of examples and practice problems on matrix multiplication.
