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 |
