Roman Numeral Tips
How Roman Numerals Work
Roman numerals use letters (I, V, X, L, C, D, M) to represent numbers. Example: 2024 = MMXXIV.
Rules
No zero. Numbers are formed by combining and subtracting values. Largest to smallest, left to right.
Examples
IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900.
