Roman Numeral Rules
The system is based on seven symbols. Their combination, following additive and subtractive rules, creates all numbers.
| Symbol | Value |
|---|---|
| I | 1 |
| V | 5 |
| X | 10 |
| L | 50 |
| C | 100 |
| D | 500 |
| M | 1,000 |
Key Rules:
- Additive: Larger symbols followed by smaller ones are added (e.g., VI = 6).
- Subtractive: A smaller symbol before a larger one is subtracted (e.g., IV = 4).
