Units Digit
A numerical digit (often shortened to just digit) or numeral is a single symbol used alone (such as "1"), or in combinations (such as "15"), to represent numbers in positional notation, such as the common base 10. The name "digit" originates from the Latin ''digiti'' meaning fingers. For any numeral system with an integer radix, base, the number of different digits required is the absolute value of the base. For example, decimal (base 10) requires ten digits (0 to 9), and Binary number, binary (base 2) requires only two digits (0 and 1). Bases greater than 10 require more than 10 digits, for instance hexadecimal (base 16) requires 16 digits (usually 0 to 9 and A to F). Overview In a basic digital system, a numeral system, numeral is a sequence of digits, which may be of arbitrary length. Each position in the sequence has a positional notation, place value, and each digit has a value. The value of the numeral is computed by multiplying each digit in the sequen ...

Period (punctuation)
The full stop (Commonwealth English), period (North American English), or full point is a punctuation mark used for several purposes, most often to mark the end of a declarative sentence (as distinguished from a question or exclamation). A full stop is frequently used at the end of word abbreviations—in British English, British usage, primarily truncations like ''Rev.'', but not after Contraction (grammar), contractions like ''Revd''; in American English, it is used in both cases. It may be placed after an initial letter used to abbreviate a word. It is often placed after each individual letter in acronyms and initialisms (e.g., "U.S."). However, the use of full stops after letters in an initialism or acronym is declining, and many of these without punctuation have become accepted norms (e.g., "UK" and "NATO"). When used in a series (typically of three, an ellipsis) the mark is also used to indicate omitted words. In the English-speaking world, a punctuation mark identical t ...

Thai Numerals
Thai numerals (, , ) are a set of numerals traditionally used in Thailand, although the Arabic numerals are more common due to extensive westernization of Thailand in the modern Rattanakosin, Rattanakosin period. Thai numerals follow the Hindu–Arabic numeral system commonly used in the rest of the world. In Thai language, numerals often follow the modified noun and precede a measure word, although variations to this pattern occur. Usage The Thai language#Nouns, Thai language lacks grammatical number. A counting, count is usually expressed in the form of an inflection, uninflected noun followed by a number and a classifier. "Five teachers" is expressed as "teacher five person" ( or with the numeral included .) "person" is a type of referent noun that is also used as the Thai part of speech called in English a Classifier (linguistics), linguistic classifier, or measure word. In Thai, counting is ''kannap'' (; ''nap'' is "to count", ''kan'' is a prefix that forms a noun from a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mayas
Maya () are an ethnolinguistic group of Indigenous peoples of Mesoamerica. The ancient Maya civilization was formed by members of this group, and today's Maya are generally descended from people who lived within that historical region. Today they inhabit southern Mexico, Guatemala, Belize, and westernmost El Salvador, Honduras, and the northernmost Nicaragua. "Maya" is a modern collective term for the peoples of the region; however, the term was not historically used by the Indigenous populations themselves. There was no common sense of identity or political unity among the distinct populations, societies and ethnic groups because they each had their own particular traditions, cultures and historical identity. It is estimated that seven million Maya were living in this area at the start of the 21st century. Guatemala, southern Mexico and the Yucatán Peninsula, Belize, El Salvador, western Honduras, and northern Nicaragua have managed to maintain numerous remnants of their an ...

Vigesimal
A vigesimal ( ) or base-20 (base-score) numeral system is based on 20 (number), twenty (in the same way in which the decimal, decimal numeral system is based on 10 (number), ten). ''wikt:vigesimal#English, Vigesimal'' is derived from the Latin adjective , meaning 'twentieth'. Places In a vigesimal Numerical digit, place system, twenty individual numerals (or digit symbols) are used, ten more than in the decimal system. One modern method of finding the extra needed symbols is to write 10 (number), ten as the letter A, or , where the 20 means radix, base , to write 19 (number), nineteen as , and the numbers between with the corresponding letters of the alphabet. This is similar to the common Computer science, computer-science practice of writing hexadecimal numerals over 9 with the letters "A–F". Another less common method skips over the letter "I", in order to avoid confusion between I20 as 18 (number), eighteen and 1 (number), one, so that the number eighteen is written as J ...

Maya Numerals
The Mayan numeral system was the system to represent numbers and calendar dates in the Maya civilization. It was a vigesimal (base-20) positional notation, positional numeral system. The numerals are made up of three symbols: Zero number#The Americas, zero (a shell), 1 (number), one (a dot) and 5 (number), five (a bar). For example, thirteen is written as three dots in a horizontal row above two horizontal bars; sometimes it is also written as three vertical dots to the left of two vertical bars. With these three symbols, each of the twenty vigesimal digits could be written. Numbers after 19 were written vertically in powers of twenty. The Mayan used powers of twenty, just as the Hindu–Arabic numeral system uses powers of ten. For example, thirty-three would be written as one dot, above three dots atop two bars. The first dot represents "one twenty" or "1×20", which is added to three dots and two bars, or thirteen. Therefore, (1×20) + 13 = 33. : Upon reaching 202 or 400 ...

Liber Abaci
The or (Latin for "The Book of Calculation") was a 1202 Latin work on arithmetic by Leonardo of Pisa, posthumously known as Fibonacci. It is primarily famous for introducing both base-10 positional notation and the symbols known as Arabic numerals in Europe. Premise was among the first Western books to describe the Hindu–Arabic numeral system and to use symbols resembling modern "Arabic numerals". By addressing the applications of both commercial tradesmen and mathematicians, it promoted the superiority of the system and the use of these glyphs. Although the book's title is sometimes translated as "The Book of the Abacus", notes that it is an error to read this as referring to the abacus as a calculating device. Rather, the word "abacus" was used at the time to refer to calculation in any form; the spelling "abbacus" with two "b"s was, and still is in Italy, used to refer to calculation using Hindu-Arabic numerals, which can avoid confusion. The book describes methods o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibonacci
Leonardo Bonacci ( – ), commonly known as Fibonacci, was an Italians, Italian mathematician from the Republic of Pisa, considered to be "the most talented Western mathematician of the Middle Ages". The name he is commonly called, ''Fibonacci'', is first found in a modern source in a 1838 text by the Franco-Italian mathematician Guglielmo Libri Carucci dalla Sommaja, Guglielmo Libri and is short for ('son of Bonacci'). However, even as early as 1506, Perizolo, a notary of the Holy Roman Empire, mentions him as "Lionardo Fibonacci". Fibonacci popularized the Hindu–Arabic numeral system, Indo–Arabic numeral system in the Western world primarily through his composition in 1202 of (''Book of Calculation'') and also introduced Europe to the sequence of Fibonacci numbers, which he used as an example in . Biography Fibonacci was born around 1170 to Guglielmo, an Italian merchant and customs official who directed a trading post in Béjaïa, Bugia, modern-day Béjaïa, Algeria ...

Western Arabic Numerals
The ten Arabic numerals (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) are the most commonly used symbols for writing numbers. The term often also implies a positional notation number with a decimal base, in particular when contrasted with Roman numerals. However the symbols are also used to write numbers in other bases, such as octal, as well as non-numerical information such as trademarks or license plate identifiers. They are also called Western Arabic numerals, Western digits, European digits, Ghubār numerals, or Hindu–Arabic numerals due to positional notation (but not these digits) originating in India. The ''Oxford English Dictionary'' uses lowercase ''Arabic numerals'' while using the fully capitalized term ''Arabic Numerals'' for Eastern Arabic numerals. In contemporary society, the terms ''digits'', ''numbers'', and ''numerals'' often implies only these symbols, although it can only be inferred from context. Europeans first learned of Arabic numerals , though their spread was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glyph
A glyph ( ) is any kind of purposeful mark. In typography, a glyph is "the specific shape, design, or representation of a character". It is a particular graphical representation, in a particular typeface, of an element of written language. A grapheme, or part of a grapheme (such as a diacritic), or sometimes several graphemes in combination (a composed glyph) can be represented by a glyph. Glyphs, graphemes and characters In modern English, symbols like letters and numerical digits are each both single graphemes and single glyphs. In most languages written in any variety of the Latin alphabet except English, the use of diacritics to signify a sound mutation is common. For example, the grapheme requires two glyphs: the basic and the grave accent . In general, a diacritic is regarded as a glyph, even if it is contiguous with the rest of the character like a cedilla in French, Catalan or Portuguese, the ogonek in several languages, or the stroke on a Polish .

Hindu–Arabic Numeral System
The Hindu–Arabic numeral system (also known as the Indo-Arabic numeral system, Hindu numeral system, and Arabic numeral system) is a positional notation, positional Decimal, base-ten numeral system for representing integers; its extension to non-integers is the decimal, decimal numeral system, which is presently the most common numeral system. The system was invented between the 1st and 4th centuries by Indian mathematics, Indian mathematicians. By the 9th century, the system was adopted by Arabic mathematics, Arabic mathematicians who extended it to include fraction (mathematics), fractions. It became more widely known through the writings in Arabic of the Persian mathematician Al-Khwārizmī (''On the Calculation with Hindu Numerals'', ) and Arab mathematician Al-Kindi (''On the Use of the Hindu Numerals'', ). The system had spread to medieval Europe by the High Middle Ages, notably following Fibonacci's 13th century ''Liber Abaci''; until the evolution of the printing pre ...
