EQUALITY SIGN Meaning and
Definition
-
The equality sign refers to a mathematical symbol, denoted as "=", used to indicate that two values or expressions are equal. It is a fundamental component of arithmetic and algebraic equations, where it serves as a relational operator, representing balance and equivalence between two entities. The symbol is composed of two parallel horizontal lines of equal length, with a slight tilt to one side, often referred to as the "equals sign."
In mathematics, the equality sign acts as a fundamental tool to express the equality between two quantities or mathematical expressions. It represents the concept that the values on both sides of the sign are the same or interchangeable. Equations utilizing the equality sign can be used to solve problems, manipulate unknown values, establish relationships between variables, or verify the validity of mathematical statements.
The equality sign is of paramount importance in basic arithmetic, algebra, and even more advanced mathematical disciplines. It is used both in numerical equations involving specific values and in algebraic equations involving variables. The symbol plays a crucial role in the principles of solving equations and manipulating mathematical expressions. By acknowledging equality through the use of the equality sign, mathematicians are able to maintain a precise and consistent representation of mathematical concepts and facilitate the understanding and communication of mathematical ideas.

Etymology of EQUALITY SIGN
The term "equality sign" refers to the mathematical symbol "=" used to indicate equality between two values. The etymology of this word can be understood by looking at the origins of both the word "equality" and the symbol itself.
The word "equality" derives from the Latin word "aequalitas", which is formed from the root "aequus" meaning "equal". The suffix "-ity" in English is used to form abstract nouns, denoting the quality or state of something. Therefore, the word "equality" conveys the concept or quality of being equal.
As for the mathematical symbol "=", it was first introduced in the 16th century by Robert Recorde, a Welsh mathematician, in his book "The Whetstone of Witte". He was in search of a symbol that stood for equality, and he chose two parallel lines of equal length.
