A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, many symbols are needed for ...

The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
In version 16.0 (September 2024), Unicode was extended with another block containing many graphics characters, Symbols for Legacy Computing Supplement, which includes a few box-drawing characters and other symbols used by obsolete operating systems (mostly from the 1970s and 1980s).
The symbol was introduced originally in 1770 by Nicolas de Condorcet, who used it for a partial differential, and adopted for the partial derivative by Adrien-Marie Legendre in 1786. [3] It represents a specialized cursive type of the letter d , just as the integral sign originates as a specialized type of a long s (first used in print by ...
The symbol may be used if the meaning is clear from context, or if it is not important whether it is interpreted as subset or as proper subset (for example, might be given as the hypothesis of a theorem whose conclusion is obviously true in the case that =).
Primarily for compatibility with earlier character sets, Unicode contains a number of characters that compose super- and subscripts with other symbols. [1] In most fonts these render much better than attempts to construct these symbols from the above characters or by using markup.
1 + x + x² + x 3 + x 4 (with ²) versus 1 + x + x 2 + x 3 + x 4 (with <sup>2</sup>). Moreover, the TeX engine used on Wikipedia may format simple superscripts using <sup>...</sup> depending on user preferences. Thus, instead of the image , many users see x 2. Formulae formatted without using TeX should use the same syntax to maintain the ...
