# Column Matrix on the Right, only

When a rectangular matrix and a column matrix are multiplied together,
the column matrix will always be on the right of the rectangular matrix.
It is only possible to multiply the two if they are **conformant**.
Two matrices are conformant if the "inner dimension" of the
each matrix is equal:

Matrix x Column Matrix = Result
N x M M x 1 = N x 1
----------------
inner dimensions
are equal

### QUESTION 4:

Do you think that it is possible to form a product that looks like this:

Row Matrix x Col. Matrix = Scalar
1 x 2 2 x 1 = 1 x 1
