    \(A\cdot B\ne A+B\) thus

    I could be wrong, but sounds as if it's asking for the "dot product" of AB and the "dot product" of CD and then their sum

    No that's in the next section. This is just asking for the sum of the two vectors giving these two points and i wanted to know if it was right.
