1. The problem statement, all variables and given/known data Find A*B^T, where A= 2 1 5 3 And B= 1 -1 1 -1 1 1 2. Relevant equations n/a 3. The attempt at a solution The problem is, is that if I get the transpose of B, I will end up with a 3x2 matrix. Isn't this impossible to multiply by a 2x2 matrix? Maybe the answers is just 'not possible', but I have a feeling I'm doing something wrong. Anybody got any pointers? Thanks!
