How Roman Numerals Work

Roman numerals use seven basic symbols: I (1), V (5), X (10), L (50), C (100), D (500), and M (1,000).

Symbols are generally written from largest to smallest, left to right, and their values are added together. However, when a smaller symbol appears immediately before a larger one, it is subtracted instead of added. This is called subtractive notation.

For example: IV = 5 − 1 = 4, and IX = 10 − 1 = 9. But VI = 5 + 1 = 6, and XI = 10 + 1 = 11.
