The Eastern Arabic numerals, also called Arabic-Hindu numerals, are the symbols used to represent numerical digits in conjunction with the Arabic alphabet in the countries of the Mashriq (the east of the Arab world), the Arabian Peninsula, and its variant in other countries that use the Persian numerals in the Iranian plateau and Asia.


The numeral system originates from an ancient Indian numeral system, which was re-introduced in the book On the Calculation with Hindu Numerals written by the Islamic Golden Age mathematician and engineer Khwarazmi, whose name was Latinized as Algoritmi.[note 1] The symbols resemble the Indian originals more than the Western Arabic Numerals.[]

Other names

These numbers are known as ?arq?m hind?yyah ( ?) in Arabic. They are sometimes also called "Indic numerals" in English.[1] However, that is sometimes discouraged as it can lead to confusion with Indian numerals, used in Brahmic scripts of India.[2]


Each numeral in the Persian variant has a different Unicode point even if it looks identical to the Eastern Arabic numeral counterpart. However, the variants used with Urdu, Sindhi, and other South Asian languages are not encoded separately from the Persian variants.

Western Arabic 0 1 2 3 4 5 6 7 8 9 10
Eastern Arabic[a] ٠ ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩ ١٠
Persian[b] ۰ ۱ ۲ ۳ ۴ ۵ ۶ ۷ ۸ ۹ ۱۰
Urdu[c] ۰ ۱ ۲ ۳ ۴ ۵ ۶ ۷ ۸ ۹ ۱۰

  3. ^ Same Unicode characters as the Persian, but language is set to Urdu. The numerals 4, 6 and 7 are different from Persian. On some devices, this row may appear identical to Persian.

Written numerals are arranged with their lowest-value digit to the right, with higher value positions added to the left. That is identical to the arrangement used for Western Arabic numerals, even though Arabic script is read from right-to-left.[3] Columns of numbers are usually arranged with the decimal points aligned.

Negative signs are written to the left of magnitudes, e.g. ?-‎ (-3).

In-line fractions are written with the numerator and denominator on the left and right of the fraction slash respectively, e.g. ?/?‎ (2/7).

The symbol ? is used as the decimal mark, as in ?‎ (3.14159265358).

The symbol ? may be used as a thousands separator, e.g. ?‎ (1,000,000,000).

Contemporary use

Eastern Arabic numerals remain strongly predominant compared to Western Arabic numerals in many countries to the East of the Arab world, particularly in Iran and Afghanistan.

In Arabic-speaking Asia as well as Egypt and Sudan both kinds of numerals are used alongside each other with Western Arabic numerals gaining more and more usage, now even in very traditional countries such as Saudi Arabia. The United Arab Emirates uses both Eastern and Western Arabic numerals.

In Pakistan, Western Arabic numerals are more extensively used. Eastern numerals still continue to see use in Urdu publications and newspapers, as well as signboards.[clarification needed]

In North Africa (excluding Egypt and Sudan), only Western Arabic numerals are now commonly used. In medieval times, these areas used a slightly different set (from which, via Italy, Western Arabic numerals derive).
