The calculator has memory slots set aside for matrices: [A], [B], ..., [J].
1. Press the MATRIX key. This brings you to a menu with a list of all the matrices.
2. Use the right-arrow twice to move over to EDIT so that you can create a matrix.
3. Type a 1 (or ENTER) for matrix [A].
4. Press 3 ENTER 3 ENTER to indicate a 3x3 matrix.
5. Now choose values of the elements of the matrix until you've filled the matrix.
6. Return to the main screen by pressing 2ND MODE.
7. Repeat the last 4 steps to create matrix B.
8. Press MATRIX then ENTER
9. Press the + button
10. Press MATRIX then 2 then ENTER
A display of the sum A + B will be shown. Use the cursor keys to move about the matrix to see all the entries.
