| To calculate AB, write down A and B next to each other (this makes it easier to see what you're solving). Then, multiply the ROWS of A by the COLUMNS of B. | |
 | |  |
|
 |
| | |
| So by this you mean, take the first row of A and the first column of B, and multiply the first entries, then the second entries, and then the third entries. | |
| | |
|
|
|
|
|
|
|
| | |
| Yes, that's exactly what I mean. | |
| | |
|
|
| | |
| So, the sum is one entry in the product matrix AB? | |
| | |
|
|
|
|
|
|
|
| | |
| Yes, you're right again. Now, you have a complete matrix: PRODUCT MATRIX. See, you're doing great! | |
| | |
|
|
| | |
| Yeah, only because you taught me. If it were anybody else, I'd be stuck. | |
