Several equal signs. In some programming languages, == and === are used to check equality, so 1844 == 1844 will return true. In PHP, the triple equal sign, ===, denotes value and type equality, [7] meaning that not only do the two expressions evaluate to equal values, but they are also of the same data type.
The triple bar or tribar, ≡, is a symbol with multiple, context-dependent meanings indicating equivalence of two different things. Its main uses are in mathematics and logic. It has the appearance of an equals sign = with a third line.
The German layout differs from the English (US and UK) layouts in four major ways: The positions of the "Z" and "Y" keys are switched. In English, the letter "y" is very common and the letter "z" is relatively rare, whereas in German the letter "z" is very common and the letter "y" is very uncommon. [1]

Dvorak keyboard layout. Dvorak / ˈdvɔːræk / ⓘ [1] is a keyboard layout for English patented in 1936 by August Dvorak and his brother-in-law, William Dealey, as a faster and more ergonomic alternative to the QWERTY layout (the de facto standard keyboard layout). Dvorak proponents claim that it requires less finger motion [2] and as a ...
≠ (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.
A tilde is also used to indicate "approximately equal to" (e.g. 1.902 ~= 2). This usage probably developed as a typed alternative to the libra symbol used for the same purpose in written mathematics, which is an equal sign with the upper bar replaced by a bar with an upward hump, bump, or loop in the middle (︍︍♎︎) or, sometimes, a tilde ...
On a typical Windows-compatible PC keyboard, the AltGr key, when present, takes the place of the right-hand Alt key. The key at this location will operate as AltGr if a keyboard layout using AltGr is chosen in the operating system, regardless of what is engraved on the key. In macOS, the Option key has functions similar to the AltGr key.

Often, a colon ':' is used instead of a vertical bar. the Sheffer stroke in logic: a | b {\displaystyle a|b} , read " a nand b ". subtraction: f ( x ) | a b {\displaystyle f (x)\vert _ {a}^ {b}} , read " f (x) from a to b ", denoting. f ( b ) − f ( a ) {\displaystyle f (b)-f (a)}
