In Algebra, the square of a number is that number multiplication by itself.

Its notation is a superscripted 2 , thus a number x squared is written as x 2. Thus: x^2 = x imes x

If x is a positive real number, the value of x 2 is equal to the area of a square (geometry) 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.
