Eastern Arabic numerals

Numerals used in the eastern Arab world and Asia Evolution of Indian numerals into Arabic and Eastern Arabic numerals along with their adoption in Europe The Eastern Arabic numerals, also called Indo-Arabic numerals, or Arabic–Indic numerals, as designated by Unicode, are the symbols used to represent numerical digits in conjunction with the Arabic script in the countries of the Mashriq (the east of the Arab world, including the Arabian Peninsula), and the variants in other countries that use the Persian numerals in greater Iran and Asia. The early Hindu–Arabic numeral system used a variety of shapes. It is unknown when the Western Arabic numeral shapes diverged from those of Eastern Arabic numerals. The Western digits 1, 2, 3, 4, 5 and 9 are clearly related, but the origins of 6, 7 and 8 are obscure. Origin The numeral system originates from an ancient Indian numeral system, which was reintroduced[to whom?][when?] during the Islamic Golden Age in the book On the Calculation with Hindic Numerals written by the Persian mathematician and engineer al-Khwarizmi, whose name was Latinized as Algoritmi.
