Parentheses
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. They come in four main pairs of shapes, as given in the box to the right, which also gives their names, that vary between British and American English. "Brackets", without further qualification, are in British English the ... marks and in American English the ... marks. Other symbols are repurposed as brackets in specialist contexts, such as those used by linguists. Brackets are typically deployed in symmetric pairs, and an individual bracket may be identified as a "left" or "right" bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context. In casual writing and in technical fields such as computing or linguistic analysis of grammar, brackets nest, with segments of bracketed material containing embedded within them other further bracketed sub-segments.

International Phonetic Alphabet
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech. The IPA is used by linguists, lexicography, lexicographers, foreign language students and teachers, speech–language pathology, speech–language pathologists, singers, actors, constructed language creators, and translators. The IPA is designed to represent those qualities of speech that are part of lexical item, lexical (and, to a limited extent, prosodic) sounds in oral language: phone (phonetics), phones, Intonation (linguistics), intonation and the separation of syllables. To represent additional qualities of speechsuch as tooth wikt:gnash, gnashing, lisping, and sounds made with a cleft lip and cleft palate, cleft palatean extensions to the International Phonetic Alphabet, extended set of symbols may be used ...

Dash
The dash is a punctuation mark consisting of a long horizontal line. It is similar in appearance to the hyphen but is longer and sometimes higher from the baseline. The most common versions are the endash , generally longer than the hyphen but shorter than the minus sign; the emdash , longer than either the en dash or the minus sign; and the horizontalbar , whose length varies across typefaces but tends to be between those of the en and em dashes. Typical uses of dashes are to mark a break in a sentence, to set off an explanatory remark (similar to parenthesis), or to show spans of time or ranges of values. The em dash is sometimes used as a leading character to identify the source of a quoted text. History In the early 17th century, in Okes-printed plays of William Shakespeare, dashes are attested that indicate a thinking pause, interruption, mid-speech realization, or change of subject. The dashes are variously longer (as in '' King Lear'' reprinted 1619) or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Function (mathematics)
In mathematics, a function from a set (mathematics), set to a set assigns to each element of exactly one element of .; the words ''map'', ''mapping'', ''transformation'', ''correspondence'', and ''operator'' are sometimes used synonymously. The set is called the Domain of a function, domain of the function and the set is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity. For example, the position of a planet is a ''function'' of time. History of the function concept, Historically, the concept was elaborated with the infinitesimal calculus at the end of the 17th century, and, until the 19th century, the functions that were considered were differentiable function, differentiable (that is, they had a high degree of regularity). The concept of a function was formalized at the end of the 19th century in terms of set theory, and this greatly increased the possible applications of the concept. A f ...

Glossary Of Mathematical Symbols
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula or a mathematical expression. More formally, a ''mathematical symbol'' is any grapheme used in mathematical formulas and expressions. As formulas and expressions are entirely constituted with symbols of various types, many symbols are needed for expressing all mathematics. The most basic symbols are the decimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), and the letters of the Latin alphabet. The decimal digits are used for representing numbers through the Hindu–Arabic numeral system. Historically, upper-case letters were used for representing points in geometry, and lower-case letters were used for variables and constants. Letters are used for representing many other types of mathematical object. As the number of these types has increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subformula
In mathematical logic, propositional logic and predicate logic, a well-formed formula, abbreviated WFF or wff, often simply formula, is a finite sequence of symbol (formal), symbols from a given alphabet (computer science), alphabet that is part of a formal language. The abbreviation wff is pronounced "woof", or sometimes "wiff", "weff", or "whiff". A formal language can be identified with the set of formulas in the language. A formula is a syntax (logic), syntactic object that can be given a semantic Formal semantics (logic), meaning by means of an interpretation (logic), interpretation. Two key uses of formulas are in propositional logic and predicate logic. Introduction A key use of formulas is in propositional logic and Higher-order logic, predicate logic such as first-order logic. In those contexts, a formula is a string of symbols φ for which it makes sense to ask "is φ true?", once any free variables in φ have been instantiated. In formal logic, Mathematical proo ...

ASCII
ASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English language focused) printable character, printable and 33 control character, control characters a total of 128 code points. The set of available punctuation had significant impact on the syntax of computer languages and text markup. ASCII hugely influenced the design of character sets used by modern computers; for example, the first 128 code points of Unicode are the same as ASCII. ASCII encodes each code-point as a value from 0 to 127 storable as a seven-bit integer. Ninety-five code-points are printable, including digits ''0'' to ''9'', lowercase letters ''a'' to ''z'', uppercase letters ''A'' to ''Z'', and commonly used punctuation symbols. For example, the letter is represented as 105 (decimal). Also, ASCII specifies 33 non-printing control codes which originated with ; most of which are now obsolete. The control cha ...

Nesting (computing)
In computing science and informatics, nestinghttps://study.com/academy/lesson/nesting-loops-stan C Programming is where information is organized in layers, or where objects contain other similar objects. It almost always refers to self-similar or recursive structures in some sense. Terminology Nesting can mean: * nested calls: ** using several levels of subroutines ** recursive calls * nested levels of parentheses in arithmetic expressions * nested blocks of imperative source code such as nested if-clauses, while-clauses, repeat-until clauses etc. * information hiding: ** nested function definitions with lexical scope ** nested data structures such as records, objects, classes, etc. * nested virtualization, also called recursive virtualization: running a virtual machine inside another virtual machine In spreadsheets In a spreadsheet functions can be ''nested'' one into another, making complex formulas.

Punctuation
Punctuation marks are marks indicating how a piece of writing, written text should be read (silently or aloud) and, consequently, understood. The oldest known examples of punctuation marks were found in the Mesha Stele from the 9th century BC, consisting of points between the words and horizontal strokes between sections. The alphabet-based writing began with no spaces, no capitalization, no vowels (see abjad), and with only a few punctuation marks, as it was mostly aimed at recording business transactions. Only with the Greek playwrights (such as Euripides and Aristophanes) did the ends of sentences begin to be marked to help actors know when to make a pause during performances. Punctuation includes Space (punctuation), space between words and both obsolete and modern signs. By the 19th century, the punctuation marks were used hierarchically, according to their weight. Six marks, proposed in 1966 by the French author Hervé Bazin, could be seen as predecessors of emoticons and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desiderius Erasmus
Desiderius Erasmus Roterodamus ( ; ; 28 October c. 1466 – 12 July 1536), commonly known in English as Erasmus of Rotterdam or simply Erasmus, was a Dutch Christian humanist, Catholic priest and Catholic theology, theologian, educationalist, Menippean satire, satirist, and philosopher. Through his Works of Erasmus, works, he is considered one of the most influential thinkers of the Northern Renaissance and one of the major figures of Dutch and Western culture. Erasmus was an important figure in classical scholarship who wrote in a spontaneous, copious and natural Latin style. As a Catholic priest developing Philology, humanist techniques for working on texts, he prepared pioneering new Vulgate, Latin and Biblical Greek, Greek scholarly editions of the Novum Instrumentum omne, New Testament and of the Church Fathers, with annotations and commentary that were immediately and vitally influential in both the Protestant Reformation and the Catholic Reformation. He also wrote ''De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italics
In typography, italic type is a cursive font based on a stylised form of calligraphic handwriting. Along with blackletter and roman type, it served as one of the major typefaces in the history of Western typography. Owing to the influence from calligraphy, italics normally slant slightly to the right, ''like so''. Different glyph shapes from roman type are usually usedanother influence from calligraphyand upper-case letters may have Swash (typography), swashes, flourishes inspired by ornate calligraphy. Historically, italics were a distinct style of type used entirely separately from roman type, but they have come to be used in conjunction—most fonts now come with a roman type and an oblique type, oblique version (generally called "italic" though often not true italics). In this usage, italics are a way to emphasise key points in a printed text, to identify many types of creative works, to cite foreign words or phrases, or, when quoting a speaker, a way to show which w ...

Uncertain Plural
An uncertain plural occurs when a writer does not know in advance whether a word should be written in the singular or plural. For English nouns, this may be demonstrated by enclosing the trailing plural or singular letters in parentheses or slashes, such as "is/are", "get(s)", "pose(s)", "fix/es", "book(s)", "answer/s" and "child(ren)". In the case of articles, "they" or "their" may be used to include a single individual, when uncertain. See also * Singular they Singular ''they'', along with its inflected or derivative forms, ''them'', ''their'', ''theirs'', and ''themselves'' (also ''themself'' and ''theirself''), is a gender-neutral third-person pronoun derived from plural they.
