CCCXXIX

CCCXXIX is the Roman numeral representation of the number 329. The Roman numeral system uses letters to denote numerical values. In this case, C represents 100, X represents 10, and V represents 5. The numeral is constructed by combining these symbols. The first C indicates 100. The second C also indicates 100, for a total of 200. The XXX signifies three tens, adding 30 to the total (200 + 30 = 230). Finally, the IX represents 9, formed by placing I (1) before X (10), which signifies subtraction (10 - 1 = 9). Therefore, CCCXXIX equals 100 + 100 + 10 + 10 + 10 + 9, which sums to 329. Roman numerals were widely used in ancient Rome and continued to be employed in Europe for centuries, particularly for numbering in books, dates, and on public buildings. While less common today, they are still encountered in specific contexts.
