The numeral system that uses digits from 0 to 7 is known as what?

• A. Binary Numeral System
• B. Decimal Numeral System
• C. Octal Numeral System
• D. Hexadecimal Numeral System

Answer: (C)

The numeral system that utilizes digits from 0 to 7 is referred to as the Octal Numeral System. This system is based on base 8, meaning it employs eight unique symbols to represent values: 0, 1, 2, 3, 4, 5, 6, and 7. Each digit position in an octal number represents a power of 8. For instance, the octal number 12 represents 18^1 + 28^0, which equals 10 in decimal.

The other systems mentioned utilize different bases. The Binary Numeral System is base 2, consisting solely of the digits 0 and 1. The Decimal Numeral System is base 10 and includes digits from 0 to 9. The Hexadecimal Numeral System, which is base 16, incorporates digits from 0 to 9 and letters A to F to extend its range. Thus, the identification of the Octal system as the one using digits from 0 to 7 is accurate.
