Number Systems

Number systems are methods for representing numbers using specific symbols and rules. The most common is the decimal system, which uses ten digits (0-9) and is familiar for daily counting. Other systems include binary (base-2), using only 0 and 1, essential for computers, and hexadecimal (base-16), using 0-9 and A-F, often used in programming. Each system has its own way of grouping and calculating numbers, but they all serve to express quantities efficiently in different contexts. Understanding different number systems helps in fields like computing, digital electronics, and data encoding.
