Vector Scalar or Not Applicable?

  1. Mar 1, 2013 #1
    1. The problem statement, all variables and given/known data

    a dot (b-c)*
    (a dot b) x c
    (a-b) x c

    Which results would yield a scalar, vector, or none?

    3. The attempt at a solution

    Please give me some guidance, I know that a dot product produces a scalar and a cross product yields a vector but what about the addition and subtractions?

    Addition and subtraction of anything always results in the same thing.
