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.[1] In an equation, it is placed between two expressions that have the same value, or for which one studies the conditions under which they have the same value.
In Unicode and ASCII, it has the code point U+003D.[2] It was invented in 1557 by Robert Recorde.
