The multiplication of a vector by a negative scalar will result in a zero vector. 14. Linear combinations of vectors can be formed by adding scalar multiples of two or more vectors. 15. If two vectors are orthogonal then their cross product equals zero. 16. The dot product of two vectors always results in a scalar. 17. You cannot do the dot product crossed with a vector (U - V) X W
