Vector

An ordered list of numbers representing a point or direction in space.

A vector in n dimensions is written as a tuple of n components. Vectors can be added entrywise and scaled by a number. Two key operations between vectors are the dot product (a scalar) and, in three dimensions, the cross product (another vector).
