Otherwise the product AB A B of two matrices does not exist.

How to multiply 2x1 matrix. In order for us to be able to multiply two matrices together the number of columns in A A has to be equal to the number of rows in B B. We can multiply any mx3 matrix A by any 3xn matrix B if A is on the left side of B. Suppose 1st matrix is of size ab and 2nd matrix is of size cd ac correspond to row and bd correspond to column.

Here a1 b2 c2 d1. Matrix multiplication between the two matrices will only be possible if bc and resulting matrix will have size ad. Link on columns vs rows In the picture above the matrices can be multiplied since the number of columns in the 1st one matrix A equals the number of rows in the 2 nd matrix B.

Notice the result of multiplying the 2x3 by the 3x1 is a 2x1 matrix. As bc we can multiply then and resulting matrix will have size ad 11. The inverse of a 1x1 matrix is simply the reciprical of the single entry in the matrix.
