Numeral System A NUMERAL SYSTEM (or SYSTEM OF NUMERATION) is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner. It can be seen as the context that allows the symbols "11" to be interpreted as the binary symbol for three, the decimal symbol for eleven, or a symbol for other numbers in different bases . The number the numeral represents is called its value. Ideally, a numeral system will: * Represent a useful set of numbers (e.g. all integers , or rational numbers ) * Give every number represented a unique representation (or at least a standard representation) * Reflect the algebraic and arithmetic structure of the numbers.For example, the usual decimal representation of whole numbers gives every nonzero whole number a unique representation as a finite sequence of digits , beginning by a nonzero digit [...More...]  "Numeral System" on: Wikipedia Yahoo 

Dzongkha Numerals Dzongkha , the national language of Bhutan Bhutan , has two numeral systems, one vigesimal (base 20), and a modern decimal system. The vigesimal system remains in robust use. Ten is an auxiliary base: the teens are formed with ten and the numerals 1–9.

Attic Numerals ATTIC NUMERALS were used by the ancient Greeks , possibly from the 7th century BC. They were also known as HERODIANIC NUMERALS because they were first described in a 2ndcentury manuscript by Herodian . They are also known as ACROPHONIC NUMERALS because the symbols derive from the first letters of the words that the symbols represent: five, ten, hundred, thousand and ten thousand. See Greek numerals Greek numerals and acrophony . DECIMAL SYMBOL GREEK NUMERAL IPA 1 Ι – – 5 Π πέντε 10 Δ δέκα 100 Η ἑκατόν 1000 Χ χίλιοι / χιλιάς 10000 Μ μύριονThe use of Η for 100 reflects the early date of this numbering system: Η (Eta ) in the early Attic alphabet represented the sound /h/. In later, "classical" Greek, with the adoption of the Ionic alphabet throughout the majority of Greece, the letter eta had come to represent the long e sound while the rough aspiration was no longer marked [...More...]  "Attic Numerals" on: Wikipedia Yahoo

Javanese Numerals The Javanese language Javanese language has a DECIMAL NUMERAL SYSTEM with distinct words for the 'tweens' from 21 to 29, called likuran. The basic numerals 1–10 have independent and combining forms, the latter derived via a suffix ng. The combining forms are used to form the tens, hundreds, thousands, and millions. The numerals 1–5 and 10 have distinct highregister (halus, or in Javanese krama) and low register (ngoko) forms. The halus forms are listed below in italics. (Dasa 10 is derived from Sanskrit désa.) Like English, Javanese has compound forms for the teens; however, it also has a series of compound 'tweens', 21–29. The teens are based on a root (wə)las, the tweens on likur, and the tens are formed by the combining forms. Hyphens are not used in the orthography, but have been added to the table below to clarify their derivation. Final orthographic a tends to in many dialects, as does any preceding a (as in sanga 9) [...More...]  "Javanese Numerals" on: Wikipedia Yahoo 

Āryabhaṭa Numeration The ĀRYABHAṭA NUMERATION is a system of numerals based on Sanskrit phonemes . It was introduced in the early 6th century in India by Āryabhaṭa , in the first chapter titled Gītika Padam of his Aryabhatiya . It attributes a numerical value to each syllable of the form consonant+vowel possible in Sanskrit phonology , from ka = 1 up to hau = 1018 . CONTENTS * 1 History * 2 Example * 3 Numeral table * 4 See also * 5 References HISTORYThe basis of this number system is mentioned in the second stanza of the first chapter of Aryabhatiya . The Varga (Group/Class) letters ka to ma are to be placed in the varga (square) places (1st, 100th, 10000th, etc.) and Avarga letters like ya, ra, la .. have to be placed in Avarga places (10th, 1000th, 100000th, etc.).

Counting Rods COUNTING RODS (traditional Chinese : 籌; simplified Chinese : 筹; pinyin : chóu; Japanese : 算木; rōmaji : sangi) are small bars, typically 3–14 cm long, that were used by mathematicians for calculation in ancient China China , Japan Japan , Korea Korea , and Vietnam Vietnam . They are placed either horizontally or vertically to represent any integer or rational number . The written forms based on them are called ROD NUMERALS [...More...]  "Counting Rods" on: Wikipedia Yahoo 

Vietnamese Numerals Historically Vietnamese has two sets of numbers: one is etymologically native Vietnamese; the other uses SinoVietnamese vocabulary. In the modern language the native Vietnamese vocabulary is used for both everyday counting and mathematical purposes. The SinoVietnamese vocabulary is used only in fixed expressions or in SinoVietnamese words. This is somewhat analogous to the way in which Latin and Greek numerals Greek numerals are used in modern English (e.g., the bi in bicycle). SinoVietnamese words are also used for units of ten thousand or above, where native vocabulary was lacking.

Inuit Numerals Inuit , like other Eskimo languages (and Celtic and Mayan languages as well), uses a vigesimal counting system. Inuit counting has subbases at 5, 10, and 15. Arabic numerals Arabic numerals , consisting of 10 distinct digits (09) are not adequate to represent a base20 system. Students from Kaktovik, Alaska , came up with the KAKTOVIK INUPIAQ NUMERALS, which has since gained wide use among Alaskan Iñupiaq , and is slowly gaining ground in other countries where dialects of the Inuit language are spoken. The numeral system has helped to revive counting in Inuit, which had been falling into disuse among Inuit speakers due to the prevalence of the base10 system in schools. The picture below shows the numerals 1–19 and then 0. Twenty is written with a one and a zero, forty with a two and a zero, and four hundred with a one and two zeros [...More...]  "Inuit Numerals" on: Wikipedia Yahoo 

Quipu QUIPUS, also known as KHIPUS or TALKING KNOTS, were recording devices historically used in a number of cultures and particularly in the region of Andean South America South America . Similar systems were used by the ancient Chinese and native Hawaiians, though this article specifically deals with the most familiar Inca Inca system, and knotted string records are often generically referred to in English as quipus after the Inca Inca term. A quipu usually consisted of colored, spun, and plied thread or strings made from cotton or camelid fiber. For the Inca, the system aided in collecting data and keeping records, ranging from monitoring tax obligations, properly collecting census records, calendrical information, and military organization. The cords contained numeric and other values encoded by knots in a base ten positional system. A quipu could have only a few or up to 2,000 cords [...More...]  "Quipu" on: Wikipedia Yahoo 

Binary Number In mathematics and digital electronics , a BINARY NUMBER is a number expressed in the BINARY NUMERAL SYSTEM or BASE2 NUMERAL SYSTEM which represents numeric values using two different symbols: typically 0 (zero) and 1 (one) .
