For that matter, they aren't really Arabic numbers, Europe got them from the Arabs though. Hindu-Arabic would be little more correct.
Liber Abaci by Leonardo of Pisa (Fibonacci) is an important interesting book to read. There he is trying to convince the readers to shift to this Hindu-Arabic system he had picked up from the Arabs.
The Fibonacci series is also introduced to the Europeans for the first time through this book. I don't recall whether he calls the series the Hindu series in this book or somewhere else. The series was known to Indian mathematicians (Pingala, Euclid's contemporary, roughly) as an enumeration sequence of short and long beats that an interval of time could be broken into.
