The glyphs in actual use are descended from Brahmi numerals and have split into various typographical variants since the Middle Ages. These symbol sets can be divided into three main families: Western Arabic numerals used in the Greater Maghreb and in Europe, Eastern Arabic numerals (also called "Indic numerals") used in the Middle East, and the Indian numerals used in South Asia.
