A well-known equality featuring the equal sign. The equals sign (British English) or equal sign (American English), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense.
In mathematics, an inequation is a statement that an inequality holds between two values. [1] [2] It is usually written in the form of a pair of expressions denoting the values in question, with a relational sign between them indicating the specific inequality relation. Some examples of inequations are:
The symbol "=" is called an "equals sign". Two objects that are not equal are said to be distinct. For example: = means that x and y denote the same object. The identity (+) = + + means that if x is any number, then the two expressions have the same value.
The less-than sign is a mathematical symbol that denotes an inequality between two values. The widely adopted form of two equal-length strokes connecting in an acute angle at the left, < , has been found in documents dated as far back as the 1560s.
≠ (not-equal sign) Denotes inequality and means "not equal". ≈ The most common symbol for denoting approximate equality. For example, ~ 1. Between two numbers, either it is used instead of ≈ to mean "approximatively equal", or it means "has the same order of magnitude as". 2.
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size. The main types of inequality are less than and greater than.
LaTeX's starred version, \operatorname* is not supported, but a workaround is to add \limits instead. For example, \operatorname{ sn }_{ b>c } (b+c) \qquad \operatorname{ sn }\limits_{ b>c } (b+c) renders as. . LaTeX does not have full support for Unicode characters, and not all characters render.
In botanical nomenclature, the triple bar denotes homotypic synonyms (those based on the same type specimen), to distinguish them from heterotypic synonyms (those based on different type specimens), which are marked with an equals sign.

Terminology for signs. When 0 is said to be neither positive nor negative, the following phrases may refer to the sign of a number: A number is positive if it is greater than zero. A number is negative if it is less than zero. A number is non-negative if it is greater than or equal to zero.
