German Keyboard Layout
The German keyboard layout is a QWERTZ keyboard layout commonly used in Austria and Germany. It is based on one defined in a former edition (October 1988) of the German standard DIN 2137-2. The current edition DIN 2137-1:2012-06 standardizes it as the first (basic) one of three layouts, calling it "T1" (', "keyboard layout 1"). 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. The German layout places "z" in a position where it can be struck by the index finger, rather than by the weaker little finger. * Part of the keyboard is adapted to include umlauted vowels (''ä'', ''ö'', ''ü'') and the sharp s (''ß''). (Some newer types of German keyboards offer the fixed assignment → ẞ for its capitalized version.) * Some of speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QWERTZ
The QWERTZ or QWERTZU keyboard is a typewriter and keyboard layout widely used in Central Europe. The name comes from the first six letters at the top left of the keyboard: ( ). Overview The main difference between QWERTZ and QWERTY is that the positions of the and keys are switched (hence the nickname "kezboard"). This change was made for three major reasons: * is a much more common letter than in German; the latter rarely appears outside words whose spellings reflect either their importation from a foreign language or the Hellenization of an older German form under the influence of Ludwig I of Bavaria. * and often appear next to each other in the German orthography, and typewriter jamming would be reduced by placing the two keys so they could be typed with separate hands. * and are also next to each other. , meaning "to" in German, and also a very common prefix can also be written very easily. Similar to many other non-English keyboards: * Part of the keyboard is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apostrophe
The apostrophe ( or ) is a punctuation mark, and sometimes a diacritical mark, in languages that use the Latin alphabet and some other alphabets. In English, the apostrophe is used for two basic purposes: * The marking of the omission of one or more letters, e.g. the contraction of "do not" to "don't". * The marking of possessive case of nouns (as in "the eagle's feathers", "in one month's time", "at your parents' ome). The word "apostrophe" comes ultimately from Greek (, ' he accent ofturning away or elision'), through Latin and French. For use in computer systems, Unicode has code points for three different forms of apostrophe. Usage in English Historical development The apostrophe was first used by Pietro Bembo in his edition of '' De Aetna'' (1496). It was introduced into English in the 16th century in imitation of French practice. French practice Introduced by Geoffroy Tory (1529), the apostrophe was used in place of a vowel letter to indicate elision (as ...

Ampersand
The ampersand, also known as the and sign, is the logogram , representing the conjunction "and". It originated as a ligature of the letters ''et''—Latin for "and". Etymology Traditionally in English, when spelling aloud, any letter that could also be used as a word in itself ("A", "I", and, " O") was prefixed with the Latin expression ('by itself'), as in "per se A". It was also common practice to add the sign at the end of the alphabet as if it were the 27th letter, pronounced as the Latin ''et'' or later in English as ''and''. As a result, the recitation of the alphabet would end in "X, Y, Z, ''and per se and''". This last phrase was routinely slurred to "ampersand" and the term had entered common English usage by 1837. It has been falsely claimed that André-Marie Ampère used the symbol in his widely read publications and that people began calling the new shape "Ampère's and". History The ampersand can be traced back to the 1st century A.D. and the old Roman c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inverted Question And Exclamation Marks
The inverted question mark, , and inverted exclamation mark, , are punctuation marks used to begin interrogative and exclamatory sentences or clauses in Spanish language, Spanish and some languages which have cultural ties with Spain, such as Asturian language, Asturian and Waray language, Waray languages. The initial marks are mirrored at the end of the sentence or clause by the 'ordinary' question mark, , or exclamation mark, . Inverted marks are supported by various standards, including ISO/IEC 8859-1, ISO-8859-1, Unicode, and SGML entity, HTML. They can be entered directly on keyboards designed for Spanish-speaking countries. Usage The inverted question mark is written before the first letter of an interrogative sentence or clause to indicate that a question follows. It is a rotated form of the standard symbol "?" recognized by speakers of other languages written with the Latin script. A normal question mark is written at the end of the sentence or clause.

5 (number)
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the for ...

Percent Sign
The percent sign (sometimes per cent sign in British English) is the symbol used to indicate a percentage, a number or ratio as a fraction of 100. Related signs include the permille (per thousand) sign and the permyriad (per ten thousand) sign (also known as a basis point), which indicate that a number is divided by one thousand or ten thousand, respectively. Higher proportions use parts-per notation. Correct style Form and spacing English style guides prescribe writing the percent sign following the number without any space between (e.g. 50%). However, the International System of Units and ISO 31-0 standard prescribe a space between the number and percent sign, in line with the general practice of using a non-breaking space between a numerical value and its corresponding unit of measurement. Other languages have other rules for spacing in front of the percent sign: * In Czech and in Slovak, the percent sign is spaced with a non-breaking space if the number is ...

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. History In the early 1600s, 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 composed of hyphens (as in Othello printed 1622); moreover, the dashes are often, but not always, prefixed by a comma, colon, or semicolon. In 1733, in Jonathan Swift's ''On Poetry'', the terms ''break'' and ''dash'' are attested for and marks: Blot out, correct, insert, ...

4 (number)
4 (four) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is tetraphobia, considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically 3, three. The sum of the first four prime numbers 2, two + 3, three + 5, five + 7, seven is the only sum of four consecutive prime numbers that yields an Parity (mathematics), odd prime number, 17 (number), seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, 3, three and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dollar Sign
The dollar sign, also known as peso sign, is a symbol consisting of a capital " S" crossed with one or two vertical strokes ($ or ), used to indicate the unit of various currencies around the world, including most currencies denominated "peso" and "dollar". The explicitly double-barred sign is called cifrão. The sign is also used in several compound currency symbols, such as the Brazilian real (R$) and the Nicaraguan córdoba (C$). The one- and two-stroke version are often considered mere stylistic (typeface) variants, although in some places and epochs one of them may have been specifically assigned, by law or custom, to a specific currency. The Unicode computer encoding standard defines a single code for both. In most English-speaking countries that use that symbol, it is placed to the left of the amount specified, e.g. "$1", read as "one dollar". History Use for the Spanish American peso in the late 1700s The symbol appears in business correspondence in the 1770s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cube (algebra)
In arithmetic and algebra, the cube of a number is its third power, that is, the result of multiplying three instances of together. The cube of a number or any other mathematical expression is denoted by a superscript 3, for example or . The cube is also the number multiplied by its square: :. The ''cube function'' is the function (often denoted ) that maps a number to its cube. It is an odd function, as :. The volume of a geometric cube is the cube of its side length, giving rise to the name. The inverse operation that consists of finding a number whose cube is is called extracting the cube root of . It determines the side of the cube of a given volume. It is also raised to the one-third power. The graph of the cube function is known as the cubic parabola. Because the cube function is an odd function, this curve has a center of symmetry at the origin, but no axis of symmetry. In integers A cube number, or a perfect cube, or sometimes just a cube, is a number wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3 (number)
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Section Sign
The section sign, §, is a typographical character for referencing individually numbered sections of a document; it is frequently used when citing sections of a legal code. It is also known as the section symbol, section mark, double-s, or silcrow. Use The section sign is often used when referring to a specific section of a legal code. For example, in Bluebook style, "Title 16 of the United States Code Section 580p" becomes "16 U.S.C. §580(p)". The section sign is frequently used along with the pilcrow (¶), which is sometimes also referred to in English as the "paragraph sign", to reference a specific paragraph within a section of a document. While is usually read in spoken English as the word ''section'', many other languages use the word "paragraph" exclusively to refer to a section of a document (especially of legal text), and use other words to describe a paragraph in the English sense. Consequently, in those cases "§" may be read as "''paragraph"'', and may occasion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
