To represent this properly, one should represent the different computations with commas in between them:Дў + 3 = 5, 5 + 6 = 11, 11 + 5 = 15 Not Equals And Other Equals Sign Variants The intention here is to represent adding the first two numbers together followed by adding another number. People will occasionally write out operations like this: Note that the sign may occasionally be used to connect steps of mathematical operations together in a non-standard way. The field of linguistics sometimes uses the equals sign to denote clitic boundaries, with the sign coming in between the word the clitic is attached to and the clitic itself. Other usages of the equals sign include the usage of the sign in chemistry, where it signals the presence of a double bond between atoms. вЂњMathematics possesses not only truth, but a supreme beauty - a beauty cold and austere, like that of sculpture.вЂќ - Bertrand Russell Meanwhile, Javascript uses the triple equals sign to indicate вЂњequality without type coercionвЂќ. Likewise, PHP uses three equals sign to make statements about value equality, showing that the expressions have equal values and share the same data type. For instance, Python uses a double equals sign (вЂњ=вЂќ) as a comparison operator since the single equals sign is used as an assignment operator. Programming languages that donвЂ™t use the equals symbol as a statement of equality have other methods of handling this equality comparison.

Languages like Perl, Python, and C continue to use the equals sign as an assignment operator, while languages like Eiffel, Asa, and APL use the equals sign to indicate equivalency. Examples of both types of use for the equals sign can be found in modern programming languages. Other computer languages may use the equals sign with the traditional вЂњequivalencyвЂќ meaning.

FORTRAN is believed to be the first computer language to make use of the equals sign, with the sign being included in revisions to FORTRAN in 1957. However, the equals sign is often used in other fields, such as in computer programming. In math, using the equals sign asserts that two statements or variables are equivalent to one another. Beyond that, Rercorde helped introduce the world at large to concepts of data manipulation and quantification, with theories and instructions on applying mathematics to various domains such as navigation, commerce, land surveying, and astronomy. RecordeвЂ™s equals sign and other contributions to mathematical theory and operators gave computer scientists a ubiquitous and universally recognized symbol to assign values and assert a quality.

It is arguable that Recorde laid the foundation for the discipline of computer science, as computer science is at its core about processing, creating, and collecting data. So the more equations you know, the more you can converse with the cosmos.вЂќ - Neil DeGrasse Tyson A vertical equals sign, rather than a horizontal equals sign, may have been used throughout the 1600s, with the now universally used horizontal equal sign becoming standardized over the course of the 1700s. This gave RecordeвЂ™s equals sign some extra influence, as when combined with + and вЂ“ the equals sign could easily be used to assert mathematical equations that took much longer to write out. However, Recorde had introduced English speakers to the now-famous German symbols for subtraction and addition: вЂњ+вЂќ and вЂњ-вЂќ. One reason that RecordeвЂ™s symbol may have been slow to catch on was that in the 16th century Latin still heavily influenced communication, and the term вЂњaequalisвЂќ was frequently just shortened to вЂњAeвЂќ or вЂњoeвЂќ if an abbreviation was required. While RecordeвЂ™s new equals sign succinctly implied equality between two values, it wasnвЂ™t widely adopted until much later.
