# Arithmetic and Common Math Symbols

A comprehensive collection of basic symbols in mathematics, along with other common symbols whose usage spans multiple mathematical subtopics.

In basic mathematics, many different symbols exist and are adopted widely. The following is a compilation of the most commonly-used symbols in arithmetic and common mathematics, along with other symbols whose usage covers multiple subfields of mathematics.

For readability purpose, these symbols are categorized by their function into tables. Other comprehensive lists of symbols — as categorized by subject and type — can be also found in the relevant pages below (or in the navigational panel).

## Mathematical Constants

In common mathematics, constants are often used to denote key natural numbers, integers, real numbers and complex numbers. The following table documents the most common of these — along with their name, usage and function.

## Delimiters

Delimiters are symbols used to signal the separation between different independent mathematical entities. These include the common delimiters such as parentheses, brackets and braces, and the use of delimiters in the context of intervals.

## Operators

Operators are placeholder symbols used to denote mathematical operations, which take one or multiple mathematical objects to another similar object. In common mathematics, these include the arithmetic operators, and other number-related unary operators.

## Relational Symbols

In mathematics, relational symbols are used to denote mathematical relations, which take one or multiple mathematical objects to form full mathematical sentences. In arithmetic and common mathematics, these include the relational symbols related to equality and comparison.

## Notational Symbols

Notational symbols are often conventions and shorthands which don’t fall into the categories of constants, delimiters, operators and relational symbols. The following table documents some of these in the context of common mathematics — along with their usage and meaning.
