Remember multiplication of matrix is row times columns:
=>
| 4 0 | | 0 1 |
| - 1 2 | | - 3 1 | =
| - 3 - 1 |
Term (1,1): 4 *0 + 0 * (-3) = 0
Term (1,2): 4*1 + 0*1 = 4
Term (2,1): -1*0 + 2*(-3) = -6
Term (2,2): -1*1 + 2*1 = 1
Term (3,1): -3*0 -1*(-3) = 3
Term (3,2): -3*1 + -1*1 = -4
Answer:
| 0 4 |
|- 6 1 |
| 3 - 4 |
