# U+00B2 SUPERSCRIPT TWO

U+00B2 was added to Unicode in version 1.1 (1993). It belongs to the block Latin-1 Supplement in the Basic Multilingual Plane.

This character is a Other Number and is commonly used, that is, in no specific script. The codepoint has the Digit value 2. The character is also known as squared.

The glyph is a Super composition of the glyphs . It has a Ambiguous East Asian Width. In bidirectional context it acts as European Number and is not mirrored. In text U+00B2 behaves as Ambiguous regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

In mathematics, a 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 32, 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 x2.

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 x + 1 is the quadratic polynomial x2 + 2x + 1.

One of the important properties of squaring, for numbers as well as in many other mathematical systems, is that (for all numbers x), the square of x is the same as the square of its additive inverse −x. That is, the square function satisfies the identity x2 = (−x)2. This can also be expressed by saying that the squaring function is an even function.
