Hindu–Arabic Numeral System The HINDU–ARABIC NUMERAL SYSTEM (also called the ARABIC NUMERAL SYSTEM or HINDU NUMERAL SYSTEM) a positional decimal numeral system , is the most common system for the symbolic representation of numbers in the world. It was invented between the 1st and 4th centuries by Indian mathematicians . The system was adopted in Arabic Arabic mathematics by the 9th century. Influential were the books of Muḥammad ibn Mūsā alKhwārizmī (On the Calculation with Hindu Hindu Numerals, c.825) and AlKindi AlKindi (On the Use of the Hindu Hindu Numerals, c.830). The system later spread to medieval Europe Europe by the High Middle Ages High Middle Ages . The system is based upon ten (originally nine) different glyphs . The symbols (glyphs) used to represent the system are in principle independent of the system itself [...More...]  "Hindu–Arabic 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.

Brahmi Numerals The BRAHMI NUMERALS are a numeral system attested from the 3rd century BCE (somewhat later in the case of most of the tens). They are the direct graphic ancestors of the modern Indian and Hindu–Arabic numerals . However, they were conceptually distinct from these later systems, as they were not used as a positional system with a zero . Rather, there were separate numerals for each of the tens (10, 20, 30, etc.). There were also symbols for 100 and 1000 which were combined in ligatures with the units to signify 200, 300, 2000, 3000, etc. ORIGINSThe source of the first three numerals seems clear: they are collections of 1, 2, and 3 strokes, in Ashoka 's era vertical I, II, III like Roman numerals Roman numerals , but soon becoming horizontal like the modern Chinese numerals . In the oldest inscriptions, 4 is a +, reminiscent of the X of neighboring Kharoṣṭhī , and perhaps a representation of 4 lines or 4 directions [...More...]  "Brahmi Numerals" on: Wikipedia Yahoo 

Egyptian Numerals The system of ancient EGYPTIAN NUMERALS was used in Ancient Egypt from around 3000 BC until the early first millennium AD. It was a system of numeration based on multiples of ten, often rounded off to the higher power, written in hieroglyphs . The Egyptians had no concept of a placevalued system such as the decimal system . The hieratic form of numerals stressed an exact finite series notation, ciphered one to one onto the Egyptian alphabet [...More...]  "Egyptian Numerals" on: Wikipedia Yahoo 

Etruscan Numerals The ETRUSCAN NUMERALS were used by the ancient Etruscans . The system was adapted from the Greek Attic numerals and formed the inspiration for the later Roman numerals Roman numerals via the Old Italic script .

Examples are known of the symbols for larger numbers, but it is unknown which symbol represents which number. Thanks to the numbers written out on the Tuscania Tuscania dice , there is agreement that zal, ci, huθ and śa are the numbers up to six (besides 1 and 5). The assignment depends on whether the numbers on opposite faces of Etruscan dice add up to seven, like nowadays. Some dice found did not show this proposed pattern [...More...]  "Etruscan Numerals" on: Wikipedia Yahoo 

Babylonian Numerals BABYLONIAN NUMERALS were written in cuneiform , using a wedgetipped reed stylus to make a mark on a soft clay tablet which would be exposed in the sun to harden to create a permanent record. The Babylonians , who were famous for their astronomical observations and calculations (aided by their invention of the abacus ), used a sexagesimal (base60) positional numeral system inherited from either the Sumerian or the Eblaite civilizations. Neither of the predecessors was a positional system (having a convention for which ‘end’ of the numeral represented the units).

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

Cyrillic Numerals CYRILLIC NUMERALS are a numeral system derived from the Cyrillic script , developed in the First Bulgarian Empire First Bulgarian Empire in the late 10th century. It was used in the First Bulgarian Empire First Bulgarian Empire and by South and East Slavic peoples Slavic peoples . The system was used in Russia as late as the early 18th century, when Peter the Great replaced it with Arabic numerals as part of his civil script reform initiative. Cyrillic numbers played a role in Peter the Great's currency reform plans, too, with silver wire kopecks issued after 1696 and mechanically minted coins issued between 1700 and 1722 inscribed with the date using Cyrillic numerals. By 1725, Russian Imperial coins had transitioned to Arabic numerals.

Georgian Numerals The GEORGIAN NUMERALS are the system of number names used in Georgian , a language spoken in the country of Georgia . The Georgian numerals from 30 to 99 are constructed using a base20 system, similar to the scheme used in Basque , French for numbers 80 through 99, or the notion of the score in English. The symbols for numbers in modern Georgian texts are the same Arabic numerals used in English, except that the comma is used as the decimal separator , and digits in large numbers are divided into groups of three using spaces or periods (full stops). An older method for writing numerals exists in which most of letters of the Georgian alphabet (including some obsolete letters) are each assigned a numeric value [...More...]  "Georgian Numerals" on: Wikipedia Yahoo

Hebrew Numerals The system of HEBREW NUMERALS is a quasidecimal alphabetic numeral system using the letters of the Hebrew alphabet . The system was adapted from that of the Greek numerals Greek numerals in the late 2nd century BC. The current numeral system is also known as the Hebrew alphabetic numerals to contrast with earlier systems of writing numerals used in classical antiquity. These systems were inherited from usage in the Aramaic and Phoenician scripts, attested from c. 800 BC in the socalled Samaria ostraca and sometimes known as HebrewAramaic numerals, ultimately derived from the Egyptian Hieratic numerals . The Greek system was adopted in Hellenistic Judaism Hellenistic Judaism and had been in use in Greece since about the 5th century BC. In this system, there is no notation for zero , and the numeric values for individual letters are added together [...More...]  "Hebrew Numerals" on: Wikipedia Yahoo 

Maya Numerals The MAYA NUMERAL SYSTEM is a vigesimal (base20) positional notation used in the Maya civilization to represent numbers. The numerals are made up of three symbols; zero (shell shape, with the plastron uppermost), one (a dot) and five (a bar). For example, thirteen is written as three dots in a horizontal row above two horizontal lines stacked above each other. 400s 20s 1s 33 429 5125 Numbers after 19 were written vertically in powers of twenty. For example, thirtythree would be written as one dot above three dots, which are in turn atop two lines. 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, another row is started (203 or 8000, then 204 or 160,000, and so on). The number 429 would be written as one dot above one dot above four dots and a bar, or (1×202) + (1×201) + 9 = 429 [...More...]  "Maya Numerals" on: Wikipedia Yahoo 

Muisca Numerals MUISCA NUMERALS were the numeric notation system used by the Muisca , one of the four advanced civilizations of the Americas Americas before the Spanish conquest of the Muisca . Just like the Mayas , the Muisca had a vigesimal numerical system, based on multiples of twenty (Chibcha : gueta). The Muisca numerals Muisca numerals were based on counting with fingers and toes. They had specific numbers from one to ten, yet for the numbers between eleven and nineteen they used "foot one" (11) to "foot nine" (19). The number 20 was the 'perfect' number for the Muisca which is visible in their calendar . To calculate higher numbers than 20 they used multiples of their 'perfect' number; guemuyhica would be "20 times 4", so 80. To describe "50" they used "20 times 2 plus 10"; guebosa asaqui ubchihica, transcripted from guêboʒhas aſaqɣ hubchìhicâ [...More...]  "Muisca Numerals" on: Wikipedia Yahoo 

Quaternary Numeral System QUATERNARY is the base 4 numeral system . It uses the digits 0, 1, 2 and 3 to represent any real number . Four is the largest number within the subitizing range and one of two numbers that is both a square and a highly composite number (the other being 36), making quaternary a convenient choice for a base at this scale. Despite being twice as large, its radix economy is equal to that of binary. However, it fares no better in the localization of prime numbers (the next best being the primorial base six, senary ). Quaternary shares with all fixedradix numeral systems many properties, such as the ability to represent any real number with a canonical representation (almost unique) and the characteristics of the representations of rational numbers and irrational numbers . See decimal and binary for a discussion of these properties [...More...]  "Quaternary Numeral System" on: Wikipedia Yahoo 

Quinary QUINARY (BASE 5 or PENTAL ) is a numeral system with five as the base. A possible origination of a quinary system is that there are five fingers on either hand . In the quinary place system, five numerals, from 0 to 4 , are used to represent any real number . According to this method, five is written as 10, twentyfive is written as 100 and sixty is written as 220. As five is a prime number, only the reciprocals of the powers of five terminate, although its location between two highly composite numbers (4 and 6 ) guarantees that many recurring fractions have relatively short periods. Today, the main usage of base 5 is as a biquinary system, which is decimal using five as a subbase . Another example of a subbase system, is sexagesimal , base 60, which used 10 as a subbase. Each quinary digit has log25 (approx. 2.32) bits of information [...More...]  "Quinary" on: Wikipedia Yahoo
