Arabic numerals
The first mentions of the numerals in the West are found in the "Codex Vigilanus" of 976.
History of the Hindu–Arabic numeral system
Its glyphs are descended from the Indian Brahmi numerals. The full system emerged by the 8th to 9th centuries, and is first described in Al-Khwarizmi's "On the Calculation with Hindu Numerals" (ca. 825), and Al-Kindi's four-volume work "On the Use of the Indian Numerals" (ca. 830). Today the name "Hindu–Arabic numerals" is usually used.
