Staff Review
This lesson shows how to take matrices that you have already entered and using a TI graphing calculator to perform operations (addition, subtraction, and multiplication) on the matrices. The steps involved in these matrix operations are shown and explained. This speeds up these operations a lot compared with doing them by hand.
