Question

Matrix A has order 4 x 8, Matrix B has order 4 x 16.
What is the order of the matrix obtained by AB?
What is the order of the matrix obtained by BA?

Answer 1

Matrix A order is 4x8.
Matrix B order is 4x16.
AB cannot result because an (m x n) can only be multiplied by an (n x p) matrix and orders don't match the requirements.
BA has the same negative result.
