Re: "Arabic Numerals"

May be one of the best if not the best book about the history
of numbers is the book:

"Les chiffres ou l'histoire d'une grande invention"
by Georges Ifrah
and of wich probably there is an English translation.

Althought Marco has already explaned it:
Digits 0, 1, 2, 3, 4, 5 , 6, 7, 8, 9 are evolved graphs from the
taken from the *occidental* arab numbers also called
"numbers ghobar"; ghobar means sand that was used
to write on it the numbers for doing operations. And arab
graphs were taken from the hindi number's graphs, i don't know
axactly from wich alphabet. In fact our digit's graphs have
a resemblance with the diferent digit's graphs in the several
alphabets used today in India.
But, as you may know, the indian alphabets have evolved from
the aramean alphabet, then after all the digit's graphs may have
some relationship with the semitic alphabet.

I like to name them "indian numbers".
