Multiplication of two matrices possible if the number of columns in the first matrix equals the number of rows in the second matrix.

The dimensions of the matrix *P* are and the number of columns in the matrix A is 3.

The dimensions of the matrix *Q* are and the number of the rows in the matrix B is 3.

The number of columns in the matrix *P* equals the number of rows in the matrix *Q*.

So, matrix product *PQ* is possible.

Its dimensions are .

The matrix product PQ is defined and matrix PQ dimensions are .
