## How do you put matrices in a graphing calculator?

To enter a matrix, press [2ND] and [x−1]. Use the right arrow key to go to the EDIT menu. Press enter to select matrix A. Type in the size of the matrix and the values by typing each number and pressing [ENTER].

**How does augmented matrix work?**

An augmented matrix for a system of equations is a matrix of numbers in which each row represents the constants from one equation (both the coefficients and the constant on the other side of the equal sign) and each column represents all the coefficients for a single variable.

### How do you enter a matrix into a graphing calculator?

### Does TI-83 have matrix?

The TI-83 has a matrix key, labeled MATRX. The matrix capability on the TI-83+ and the TI-84 will be found above the x-1 key, and will be labeled MATRX or MATRIX. For simplicity, the word MATRIX is used throughout this document. each entry.

**Can you use matrices on a TI-84 Plus?**

Matrices are the perfect tool for solving systems of equations (the larger the better). Fortunately, you can work with matrices on your TI-84 Plus. All you need to do is decide which method you want to use. What do the A and B represent? The letters A and B are capitalized because they refer to matrices.
