A basis is a set of these. The parallelogram rule is used for adding these objects. One operation involving them is only valid in three or seven dimensions, and another operation involving them uses the product of the lengths of two of them and the cosine of the angle between them. Those operations are the (*) cross product and the dot product. For 10 points, name these objects which have both magnitude and direction, unlike scalars.
