Coordinate system

A coordinate system is a system of numbers used to uniquely determine the position of a point. For two-dimensional systems, the numbers (scalars) are in ordered pairs. More dimensions call for more numbers. 

For example, (3) is one-dimensional, (1, 4) is two-dimensional, (1, 5, 9) is three-dimensional, (2, 6, 5, 3) is four-dimensional, and (5, 8, 9, 7, 9) is five-dimensional.
