- I = 1 | V = 5 | X = 10 | L = 50 | C = 100 | D = 500 | M = 1000
The subtractive rule: a smaller symbol before a larger one is subtracted. IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900.
- 1 = I | 4 = IV | 5 = V | 9 = IX | 10 = X | 14 = XIV | 40 = XL | 50 = L
- 90 = XC | 100 = C | 400 = CD | 500 = D | 900 = CM | 1000 = M | 1999 = MCMXCIX | 2024 = MMXXIV | 2025 = MMXXV

Frequently Asked Questions :
2026 in Roman numerals is MMXXVI. Breakdown: MM = 2000 + XX = 20 + VI = 6 = 2026.
IV uses the subtractive rule: I (1) placed before V (5) means 5−1 = 4. You cannot write IIII because symbols cannot be repeated more than three consecutive times. Some traditional clock faces still use IIII, but IV is the standard form.
In standard notation, the largest expressible number is 3999 (MMMCMXCIX). Using M four times (MMMM) would violate the three-repetition rule. Extended systems using overbars (Vinculum) can represent larger numbers, but these are rarely encountered in everyday use.
