Multiplying the matrices A and B would yield the following matrix:
| 1 0 |
| 0 1 |
A simple method would be using a calculator to solve for this. You can input the values of one matrix, and then the values of another matrix, then multiply them and it would yield the above result. As a rule of thumb, you make sure to only multiply similar matrices.
