Standard notation for an equivalence relation. Often used for denoting other types of similarity, for example, matrix similarity or similarity of geometric shapes.

Denotes the asymptotic equivalence of two functions or sequences. Between two numbers, either it is used instead of ≈ to mean 'approximatively equal', or it means 'has the same order of magnitude as'. For having more symbols, other typefaces are also used, mainly boldface a, A, b, B, … (for a more accurate approximation, see pi). In mathematical formulas, the standard typeface is italic type for Latin letters and lower-case Greek letters, and upright type for upper case Greek letters. As the number of these sorts has remarkably increased in modern mathematics, the Greek alphabet and some Hebrew letters are also used. Letters are used for representing many other sorts of mathematical objects. Historically, upper-case letters were used for representing points in geometry, and lower-case letters were used for variables and constants. The decimal digits are used for representing numbers through the Hindu–Arabic numeral system. The most basic symbols are the decimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), and the letters of the Latin alphabet. As formulas are entirely constituted with symbols of various types, many symbols are needed for expressing all mathematics. ( Discuss) Proposed since August 2023.Ī 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. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.

It has been suggested that List of mathematical symbols by subject be merged into this article. Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
