     Which of the following products of vector functions (A, B C, and D) do not make sense? Explain.  x(A+|B|) C.(AxB + D) (AxB)xV-C - D  (A-B - D)  (A-C + |B|)  
  
  Solution
1) This does not make sense since curl acts on vectors but |B| is a scalar
3) This does not make sense as del.C is a scalar
4) A.B does not make sense so A.B-D does not make sense
