![]() The numerals themselves were referred to in the west as ashkāl al‐ghubār ("dust figures") or qalam al-ghubår ("dust letters"). The use of the dust board appears to have introduced a divergence in terminology as well: whereas the Hindu reckoning was called ḥisāb al-hindī in the east, it was called ḥisāb al-ghubār in the west (literally, "calculation with dust"). Ĭalculations were originally performed using a dust board ( takht, Latin: tabula), which involved writing symbols with a stylus and erasing them. Some amount of consistency in the Western Arabic numeral forms endured from the 10th century, found in a Latin manuscript of Isidore of Seville's Etymologiae from 976 and the Gerbertian abacus, into the 12th and 13th centuries, in early manuscripts of translations from the city of Toledo. The Western Arabic numerals came to be used in the Maghreb and Al-Andalus from the 10th century onward. They show three forms of the numeral "2" and two forms of the numeral "3", and these variations indicate the divergence between what later became known as the Eastern Arabic numerals and the Western Arabic numerals. The oldest specimens of the written numerals available are from Egypt and date to 873–874 CE. In the eastern part of the Arabian Peninsula, the Arabs were using the Eastern Arabic numerals or "Mashriki" numerals: ٠ ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩ Īl-Nasawi wrote in the early 11th century that mathematicians had not agreed on the form of the numerals, but most of them had agreed to train themselves with the forms now known as Eastern Arabic numerals. The reason the digits are more commonly known as "Arabic numerals" in Europe and the Americas is that they were introduced to Europe in the 10th century by Arabic speakers of Spain and North Africa, who were then using the digits from Libya to Morocco. However this was done with different symbols.Įvolution of Indian numerals into Arabic numerals and their adoption in Europe The numerals have found worldwide use significantly beyond the contemporary spread of the Latin alphabet, and have become common in the writing systems where other numeral systems existed previously, such as Chinese and Japanese numerals.ĭecimal notation was developed in India, with expansion to non-integers in Arabia. ![]() European trade, books, and colonialism helped popularize the adoption of Arabic numerals around the world. Two centuries later, in the Algerian city of Béjaïa, the Italian scholar Fibonacci first encountered the numerals his work was crucial in making them known throughout Europe. The term numbers or numerals or digits often implies only these symbols, however this can only be inferred from context.Įuropeans learned of Arabic numerals about the 10th century, though their spread was a gradual process. The Oxford English Dictionary differentiates them with the fully capitalized Arabic Numerals to refer to the Eastern digits. They are also called Western Arabic numerals, Ghubār numerals, Hindu-Arabic numerals, Western digits, Latin digits, or European digits. ![]() The term often implies a decimal number, in particular when contrasted with Roman numerals. They are also used for writing numbers in other systems such as octal, and for writing identifiers such as computer symbols, trademarks, or license plates. Arabic numerals are the ten symbols most commonly used to write decimal numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. ![]()
