How many numbers are in the hindu-arabic numeration system?

Answer 1

There are an infinite amount of numbers. However, there are only 10 numeric symbols, 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The symbols are independent of the system. These are the Latin symbols, now internationally recognised, however many cultures still use their own traditional symbols. Punctuation symbols are also used to format a number, such as the radix point (.) and factors of 1000 (,) however some cultures, particularly non-English speaking European cultures, use these symbols the other way around.
