B is matrix of order (3 x 1) and A is a matrix of order (2 x 3) For two matrices to be able to be multiplied the no. of columns of the first matrix should be equal to the no. of rows of the second matrix. And Matrix multiplication is not commutative. AB not equal to BA If I do AB, A is (2 x 3) (Meaning 2 rows and 3 columns) B is (3 x 1) Which means 3 rows and 1 column. No. of columns of A match No. of Rows of B. So you can multiply them. But if you want to BA, B is 3 x 1 and A is 2 x 3 Columns of B does not match rows of A. So you cannot do BA. AB is possible but BA is not possible
