The picture I included shows how to to a 2x2 and 2x1 matrix multiplication if that’s what you’re confused about.

If you’re wondering what you can learn from the example. The product matrices on the left are the same except the terms in top matrix each have an added term. So the difference between the two sets of matrices result in the top having two extra terms after the multiplication.

Let me know if you still need more.
