1. Repetition Rule: The symbols I, X, C, and M can be repeated up to three times in a row. Example: III = 3, XXX = 30, CCC = 300.

2. Addition Rules: When smaller numerals follow larger ones, they are added. Example: VI = 5 + 1 = 6, CCCXXXIII = 300 + 30 + 3 = 333.

3. Subtraction Rules: When a smaller number comes before a larger number, it is subtracted. Example: IV = 5 - 1 = 4.

4. Non-Repeatable Symbols: V (5), L (50), and D (500) are never repeated or subtracted.

5. Descending Order: Numerals are written from largest to smallest, left to right.
