Let be a Vector Space over a Field , and let be a nonempty Set. Now define addition for any Vector and element subject to the conditions
In an affine space, it is possible to fix a point and coordinate axis such that every point in the Space can be represented as an -tuple of its coordinates. Every ordered pair of points and in an affine space is then associated with a Vector .
