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 Recorde’s equals sign some extra influence, as when combined with + and – 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: “+” and “-”. One reason that Recorde’s symbol may have been slow to catch on was that in the 16th century Latin still heavily influenced communication, and the term “aequalis” was frequently just shortened to “Ae” or “oe” if an abbreviation was required. While Recorde’s new equals sign succinctly implied equality between two values, it wasn’t widely adopted until much later.

Recorde is reported to have found the act of having to repeatedly state that two values were equal to one another time consuming and irritating, developing a shorthand to convey the meaning of equivalency. Recorde was a Welsh Mathematician who first used a much larger, wider equals sign to represent two equivalent items, calling them parallel lines or “Gemowe lines” (twin lines). It is believed that the equals sign was invented around 1557 by Robert Recorde. The word “equals” is believed to come from the Latin term “æqualis” which can be translated roughly as “even”, “identical”, or “uniform”. – Transferred from en.wikipedia to Commons., Public Domain, Photo: By The original uploader was Lumos3 at English Wikipedia. Most keyboards have a shortcut for writing the equals sign, located above the brackets on a QWERTY keyboard layout. The equals/equality sign is a mathematical symbol used to assert equality between two expressions. Charts and character databases exist to look up special characters.

Special Unicode and ASCII characters, characters that are not present on a keyboard, can be typed by using a series of commands, such as pressing down ALT and typing in a corresponding number for ASCII characters.

The American Standard Code for Information Interchange, or ASCII, is an older encoding standard succeeded by Unicode, though it still is in use in many places.

Unicode characters are widely used in computer software and programming languages, thanks to providing a consistent standard for operating systems and languages. The Unicode consortium contains over 137,000 characters covering different languages, scripts, symbols, and even emojis. Unicode is a system of standardization for the encoding and display of text characters and symbols. Special characters like the “does not equal” or inequality symbol are typed with certain Unicode characters. “Mathematics is not about numbers, equations, computations, or algorithms it is about understanding.” - William Paul Thurston What Is Unicode/ASCII?
