Once people came to an abstract idea of a number, they had to write it in some way. Probably, the most primitive numerical system is when a number is represented by a corresponding set of vertical bars. Romans invented a new system based on character representation of different numbers (one thousand is symbolized by M, one hundred by letter C etc.) Contemporary positional numerical system (for instance, 10-based) needs some mathematical foundation, namely a theorem of existance and uniqueness of positional representation.
