The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
In high-level computer programming and digital electronics, logical conjunction is commonly represented by an infix operator, usually as a keyword such as "AND", an algebraic multiplication, or the ampersand symbol & (sometimes doubled as in &&). Many languages also provide short-circuit control structures corresponding to logical conjunction.
In Jan Łukasiewicz's prefix notation for logic, the operator is , short for Polish alternatywa (English: alternative). [ 4 ] In mathematics, the disjunction of an arbitrary number of elements a 1 , … , a n {\displaystyle a_{1},\ldots ,a_{n}} can be denoted as an iterated binary operation using a larger ⋁ (Unicode U+22C1 ⋁ N-ARY LOGICAL ...
Negation: the symbol appeared in Heyting in 1930 [2] [3] (compare to Frege's symbol ⫟ in his Begriffsschrift [4]); the symbol appeared in Russell in 1908; [5] an alternative notation is to add a horizontal line on top of the formula, as in ¯; another alternative notation is to use a prime symbol as in ′.
References on English usage strongly criticize the phrase as "ugly" [2] and "Janus-faced". [4] William Strunk, Jr., and E.B. White, in their classic The Elements of Style–recognized by Time one of the 100 best and most influential non-fiction books written in English since 1923, [6] say and/or is "A device, or shortcut, that damages a sentence and often leads to confusion or ambiguity". [3]
The Computer Modern fonts replace it with an "E.T." symbol in the cmti# (text italic) fonts, so it can be entered as {\it\&} in running text when using the default (Computer Modern) fonts. [ 39 ] In Microsoft Windows menus, labels, and other captions, the ampersand is used to denote the next letter as a keyboard shortcut (called an "Access key ...

The stroke is named after Henry Maurice Sheffer, who in 1913 published a paper in the Transactions of the American Mathematical Society [10] providing an axiomatization of Boolean algebras using the stroke, and proved its equivalence to a standard formulation thereof by Huntington employing the familiar operators of propositional logic (AND, OR, NOT).
