CMLVI

CMLVI is a Roman numeral representation. To understand its value, we break down the individual Roman numeral symbols. C represents 100, M represents 1000, L represents 50, and VI represents 6 (V is 5 and I is 1). In Roman numerals, when a smaller numeral is placed before a larger numeral, it indicates subtraction. However, in CMLVI, the M is preceded by a C. This means CM represents 900 (1000 - 100). The L follows the CM, indicating addition. So far, we have 900 + 50 = 950. Finally, VI represents 6. Therefore, CMLVI is the sum of CM, L, and VI, which equals 900 + 50 + 6, resulting in the Arabic numeral 956. This number, 956, is the modern decimal equivalent of the Roman numeral CMLVI. The system of Roman numerals uses a combination of letters to denote numerical values, with specific rules governing their placement to determine the overall quantity.
