Let's use these
matrices:
Let's find
 :
I do these by
stacking...

![A is [ row 1: -1 , 5 row 2: 2 , -3 ]](images/04-matrices-11.gif)
![B is [ row 1: 0 , 9 row 2: 8 , -6 row 3: 4 , 7 ] ... place an empty matrix of size m x p next to matrix B and below matrix A](images/04-matrices-12.gif) |
The answer goes here. |
We just do an
intersecting row and column thing:
![A = [ row 1: -1 , 5 row 2: 2 , -3 ] ... B = [ row 1: 0 , 9 row 2: 8 , -6 row 3: 4 , 7 ] ... 18 goes in c11 of the answer matrix c](images/04-matrices-15.gif) |
To fill this spot, we multiply
and add:

![A = [ row 1: -1 , 5 row 2: 2 , -3 ] ... B = [ row 1: 0 , 9 row 2: 8 , -6 row 3: 4 , 7 ] ... use column 1 of matrix A and row 1 of matrix B and see where they intersect in the answer matrix c](images/04-matrices-13.gif)
