Arabic numerals
The first mentions of the numerals in the West are found in the "Codex Vigilanus" of 976.
Liber Abaci
"Liber Abaci" was among the first Western books to describe the Hindu–Arabic numeral system and to use symbols traditionally described as "Arabic numerals". By addressing the applications of both commercial tradesmen and mathematicians, it contributed to convincing the public of the superiority of the system, and the use of these glyphs.
