# 2D Space Notation

In math, two dimensional space is denoted using the (set of real numbers) symbol raised to the second power. For example, this notation typically appears in text like this.

In plain language, this expression represents the set of real number pairs that define the points that make up the 2D coordinate plane. One of the points in this set can be drawn as a point in 2D space with an -coordinate and -coordinate like so.
