Kaktovik Inupiaq 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, 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,[1] 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.[2] 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 [...More...]  "Kaktovik Inupiaq Numerals" on: Wikipedia Yahoo 

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 with a nonzero digit [...More...]  "Numeral System" on: Wikipedia Yahoo

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 [...More...]  "Etruscan Numerals" on: Wikipedia Yahoo 

Georgian Numerals The Georgian numerals 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,[1][2][3] similar to the scheme used in Basque, French for numbers 80 through 99,[4] 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[5] or periods (full stops) [...More...]  "Georgian Numerals" on: Wikipedia Yahoo

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 Samaria ostraca and sometimes known as HebrewAramaic numerals, ultimately derived from the Egyptian Hieratic numerals.

Attic Numerals 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.

Babylonian Numerals 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.[1] Neither of the predecessors was a positional system (having a convention for which ‘end’ of the numeral represented the units).Contents1 Origin 2 [...More...]  "Babylonian Numerals" on: Wikipedia Yahoo 

Brahmi Numerals The Brahmi numerals 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. Origins[edit] The 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, 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 

Chuvash Numerals Chuvash numerals Chuvash numerals is an ancient numeral system from the Old Turkic script the Chuvash people Chuvash people used. (Modern Chuvash use HinduArabic numerals.)

Āryabhaṭa Numeration The Āryabhaṭa numeration 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 Sanskrit phonology, from ka = 1 up to hau = 1018.Contents1 History 2 Example 3 Numeral table 4 See also 5 ReferencesHistory[edit] The basis of this number system is mentioned in the second stanza of the first chapter of Aryabhatiya.

Maya Numerals The Mayan numeral system was the system to represent numbers and calendar dates in the Maya civilization. It was a vigesimal (base20) positional numeral system. 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 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.400s20s1s33 429 5125Numbers after 19 were written vertically in powers of twenty. The Mayan used powers of twenty, just as our HinduArabic numeral system uses powers of tens.[1] For example, thirtythree 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 [...More...]  "Maya Numerals" on: Wikipedia Yahoo
