The Greek alphabet has 24 letters; three additional letters had to be incorporated in order to reach 900. Unlike the Greek, the Hebrew alphabet's 22 letters allowed for numerical expression up to 400. The Arabic abjad's 28 consonant signs could represent numbers up to 1000. Ancient Aramaic alphabets had enough letters to reach up to 9000.
The Oxford English Dictionary uses lowercase Arabic numerals while using the fully capitalized term Arabic Numerals for Eastern Arabic numerals. [3] In contemporary society, the terms digits, numbers, and numerals often implies only these symbols, although it can only be inferred from context.
The Abjad numerals are a decimal numeral system in which the 28 letters of the Arabic alphabet are assigned numerical values. From Wikipedia, the free encyclopedia.
Those letters that do not have a close phonetic approximation in the Latin script are often expressed using numerals or other characters, so that the numeral graphically approximates the Arabic letter that one would otherwise use (e.g. ع is represented using the numeral 3 because the latter looks like a vertical reflection of the former).
The Hindu–Arabic system is designed for positional notation in a decimal system. In a more developed form, positional notation also uses a decimal marker (at first a mark over the ones digit but now more commonly a decimal point or a decimal comma which separates the ones place from the tenths place), and also a symbol for "these digits recur ad infinitum".
So too are the thousands, with the number of thousands followed by the word "thousand". The number one thousand may be written 1 000 or 1000 or 1,000; larger numbers are written for example 10 000 or 10,000 for ease of reading. European languages that use the comma as a decimal separator may correspondingly use the period as a thousands separator.
The Devanagari numerals are the symbols used to write numbers in the Devanagari script, predominantly used for northern Indian languages. They are used to write decimal numbers, instead of the Western Arabic numerals .
Modern Arabic mathematical notation is a mathematical notation based on the Arabic script, used especially at pre-university levels of education. Its form is mostly derived from Western notation, but has some notable features that set it apart from its Western counterpart.
