CCXCVIII

CCXCVIII is the Roman numeral representation of the number 298. Roman numerals are a numeral system that originated in ancient Rome. They are composed of letters from the Latin alphabet, each representing a specific value. The system uses a combination of additive and subtractive principles to denote numbers.

In the case of CCXCVIII, the letters are interpreted as follows: C represents 100, X represents 10, V represents 5, and I represents 1. The numeral is read from left to right. Two C's together (CC) signify 100 + 100 = 200. The XC combination indicates a subtractive principle where X (10) is placed before C (100), meaning 100 - 10 = 90. Following this, V (5) is added, and then three I's (III) are added, representing 1 + 1 + 1 = 3. Therefore, CCXCVIII is calculated as 200 + 90 + 5 + 3, which equals 298. This system was widely used throughout Europe for centuries and continues to be seen in contexts such as clock faces, chapter headings, and regnal numbers.
