Which numbering system is commonly used and includes the digits 0-9?

• A. Hexadecimal
• B. Binary
• C. Denary
• D. Octal

Answer: (C)

The denary, also known as the decimal system, is the numbering system most commonly used in everyday life. It consists of ten unique digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. This base-10 system facilitates calculations and is intuitive for humans, as it directly corresponds to the number of fingers on two hands. In contrast, other systems like hexadecimal (base-16) include digits 0-9 and additional symbols A-F, binary (base-2) employs only 0 and 1, while octal (base-8) uses digits from 0 to 7. The denary system's widespread usage makes it the most familiar and practical numbering system for general applications.
