thanks so much.

]]>yes they are two 3 x 3 matrices. So for the second row of AB it would be [15 1 2] ?

It didn't say to multiply so I wasn't sure that I worked the problem correctly but if you have A matrix B matrix and you have to come up with the second row of AB for the matrices, was I correct in assuming that I was to multiply?

Thanks so much.

]]>I know how to go through the process of multiplication for the matrices. I am just not sure that is what the question was asking me to do.

]]>That's correct.

{7/3} : I think those are two 3 x 3 matrices.

]]>Let A=[-2 1 3] and B = [0 1 -3]. Find the second row of AB.

1 0 5 1 3 -4

0 4 2 3 0 1

I multiplied and for the second row of AB, I got [15 1 2]

Is this correct?
