Matrixes/Matrices

No, this has nothing to do with the movie. How do you multiply matrices? The saddest thing about all of this is even my book tells me to do it by calculator. :-/ Sad, really.

Multiply Row 1 from A with Column 2 from B
P.S Orenda, are you doing linear algebra? What program are you in again?
I never had to multiply matrices to this point, not even high school. I just happen to know that much.
Say row 1 of matrix a is {2 1 -6} and column 1 of B is {1 0 -2}.
