Description:  This shows users the mechanics of matrix muliplication using color coding and how each entry in the solution matrix is derived. The user can scroll down and practice multiplying matrices. After determining if the matrices can or cannot be multiplied the user clicks on the appropriate button. Unfortunately, the majority of the problems cannot be mutliplied. For those that can be multiplied users are required to give the dimensions of the answer matrix and then type in the entry for the solution matrix. Feedback is given for all user entries.
