| Select the program. | [ RUN ] { MTH } { --> } { MAT } { A*B } { NEW } |
 |
| Enter the number of rows in matrix A | 3 { rA } |  |
| Enter the number of columns in matrix A | 3 { cA } |  |
| Enter the number of columns in matrix B | 2 { cB } |  |
| Proceed with program | { EOD } |  |
| Enter the A matrix | 12 { ENT } |  |
| 9 { ENT } |  |
|
| 12 { ENT } |  |

| Reuse matrix A | { NXT } { OLD } |  |
| Enter the number of columns in matrix B | 1 { cB } |  |
| Proceed with program | { EOD } |  |
| Enter the first column of matrix B | 5 { ENT } |  |
| 4 { ENT } |  |
|
| 4 { ENT } |  |
|
| Proceed with program | { NO } |  |
| View matrix C | { NXT } |  |
