What is the term for the number system that uses a combination of ten digits ranging from 0 to 9?

The number system that uses a combination of ten digits ranging from 0 to 9 is known as the decimal system. This base-10 system is the most commonly used number system in everyday life, primarily because it aligns with human counting methods, which typically involve ten fingers. Each digit in this system represents an increment in powers of ten, making it straightforward and intuitive for performing calculations and expressing values.

In contrast, the binary system, which uses only two digits (0 and 1), is crucial in computer science and digital electronics. The hexadecimal system, with its sixteen symbols (0-9 and A-F), is extensively used in programming as a more compact way to represent binary data. The octal system operates on base-8, utilizing eight digits (0 to 7) and has historical significance in computing. However, none of these systems employ the complete range of ten digits as found in the decimal system, which is why the correct answer is specifically identified as decimal.
