- If A and B are matrices with the same dimension and k is a real number, how do you find A+B and kA ?arrow_forwardIn a previous section, we showed that matrix multiplication is not commutative, that is, ABBA in most cases. Can you explain why matrix multiplication is commutative for matrix inverses, that is, A1A=AA1 ?arrow_forwardAre the two matrices similar? If so, find a matrix P such that B=P1AP. A=[100020003]B=[300020001]arrow_forward
