Why do you use 0 to 9 as the symbols in the base 10 number system?

The base 10 number system uses the symbols 0 to 9 because it is a positional numeral system based on ten digits, which corresponds to the number of fingers humans typically have. This choice of symbols allows for efficient representation of numbers through combinations of these digits in various places, each representing increasing powers of ten. The use of 0 as a placeholder is crucial for distinguishing between values like 10 and 100. Overall, this system facilitates arithmetic operations and has become the most widely used numeral system globally.
