Performing the triple product on three of these entities gives the volume of a parallelepiped.   
Performing the triple product on three of these entities gives the volume of a parallelepiped.   The right hand rule can be used when performing an operation on them, and these entities  can be added using the (*) parallelogram rule. Two of them are perpendicular if their dot product  equals zero. For 10 points, name these mathematical entities that have both magnitude and  direction and are contrasted with scalars.
