A numeral system, or system of numeration, refers to a structured method of representing numbers through the use of digits or symbols according to specific rules. In mathematics, a number system establishes the framework for expressing, interpreting, and performing operations on numbers. Each system is characterised by its base , which defines the positional value and structure of the numbers it represents.
The value of each digit in a number can be determined using −
- The digit
- The position of the digit in the number
- The base of the number system (where the base is defined as the total number of digits available in the number system)
