CMLIX

CMLIX is a Roman numeral. It represents the number 959 in the Arabic numeral system. The Roman numeral system uses letters to denote numerical values. C represents 100, M represents 1000, L represents 50, and IX represents 9. In the case of CMLIX, the 'CM' signifies 900 because a smaller numeral (C=100) placed before a larger numeral (M=1000) indicates subtraction. Similarly, 'IX' signifies 9 because the 'I' (1) is placed before the 'X' (10), indicating subtraction. Therefore, CMLIX is calculated as (1000 - 100) + (10 - 1) = 900 + 9 = 959. Roman numerals were used extensively in ancient Rome and continued to be used in Europe for various purposes, including numbering and dating, for centuries. Understanding the rules of Roman numeral formation is key to deciphering their values.
