Because we use the decimal system which has only ten symbols - for the numbers 0 to 9. In the decimal system, every time you get to a power of ten, the number starts one further place to the left.

The symbols used in the Hindu/Arabic system of numbers are; 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0.

Hindu-Arabic basic numeral symbols are: 0 1 2 3 4 5 6 7 8 and 9 Roman basic numeral symbols are: I V X L C D and M

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.

The original Greek numeral system was the Aegean numeral system, which used separate symbols for 1, 10, 100, 100 and 10000. This was replaced by the Attic numeral system, which was quite similar to the Etruscan/Roman numeral system (which derived from it), with separate symbols for 1, 5, 10, 50, 100 and so on. This was then replaced by the Ionic system, which used 27 separate symbols for the units 1-9, the tens 10-90 and the hundreds 100-900.
