Learn how to add, subtract, and multiply matrices on a graphing calculator.
- How do you add, subtract, and multiply matrices on a TI graphing calculator?
- What happens if you try to add or subtract two matrices with different dimensions on a TI graphing calculator?
- How can you access matrices on a TI graphing calculator after entering them?
- What does ERR:DIM MISMATCH mean with matrices on a TI graphing calculator?
- How do you multiply a number by a matrix on a TI graphing calculator?
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.
