Square (algebra)

From Wikipedia, the free encyclopedia.
In algebra, the square of a number is that number multiplied by itself.

Its notation is a superscripted "2", thus a number x squared is written as x2. Thus:

If x is a positive real number, the value of x2 is equal to the area of a square of edge length x.

A positive integer that is the square of some other integer, for example 25 which is 52, is known as a square number, or more simply a square.
