Numeral System

A numeral system is a method used to express numbers using a set of symbols, called digits, arranged in a specific way. It defines how numbers are written, read, and understood. The most common system is the decimal system, which uses ten digits (0-9). Other systems include binary (base-2, using 0 and 1), used in computers, and hexadecimal (base-16, using 0-9 and A-F). Numeral systems provide a consistent way to represent quantities, perform calculations, and communicate numerical information across different contexts and technologies.
