*square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 3*^{2}, which is the number 9.*In some cases when superscripts are not available, as for instance in programming languages or plain text files, the notations*x*^2 or*x***2 may be used in place of*x^{2}.The adjective which corresponds to squaring is

*quadratic*.The square of an integer may also be called a square number or a perfect square. In algebra, the operation of squaring is often generalized to polynomials, other expressions, or values in systems of mathematical values other than the numbers. For instance, the square of the linear polynomial is the quadratic polynomial .

One of the important properties of squaring, for numbers as well as in many other mathematical systems, is that (for all numbers ), the square of is the same as the square of its additive inverse . That is, the square function satisfies the identity . This can also be expressed by saying that the squaring function is an even function.
