Stated simply, a numbersystem is a set of objects (often numbers), operations, and the rules governing those operations.
One example is our familiar real numbersystem, which uses base ten numbers and such operations as addition and multiplication.
Before we begin to analyze the real numbersystem, we will first examine a finite numbersystem -- its elements (which, unlike the real numbersystem, are limited in number), its operations, and the rules that govern it.
NumberSystems, in mathematics, various notational systems that have been or are being used to represent the abstract quantities called numbers.
A numbersystem is defined by the base it uses, the base being the number of different symbols, or numerals, required by the system to represent any of the infinite series of numbers.
