Understanding Roman Numerals
Roman numerals are a numeral system that originated in ancient Rome. Numbers are represented by combinations of letters from the Latin alphabet.
Basic Symbols
| Symbol | I | V | X | L | C | D | M |
|---|---|---|---|---|---|---|---|
| Value | 1 | 5 | 10 | 50 | 100 | 500 | 1000 |
Rules of Formation
1. Addition: When a symbol appears after a larger or equal symbol, it is added. (e.g., VI = 5 + 1 = 6; XX = 10 + 10 = 20).
2. Subtraction: When a symbol appears before a larger symbol, it is subtracted. This is only used for specific pairs. (e.g., IV = 5 - 1 = 4; XC = 100 - 10 = 90).
3. Repetition: A symbol can be repeated up to three times in a row. V, L, and D are never repeated.
