Arabic numerals milestone in the development of mathematics. One may distinguish between this positional "system", which is identical throughout the family, and the precise glyphs used to write the numerals, which varied regionally.

"Algoritmi", the translator's rendition of the author's name, gave rise to the word "algorithm". The first mentions of the numerals in the West are found in the "Codex Vigilanus" of 976. From the
