Basic Rules for Writing Roman Numerals

• Roman numerals use seven symbols: I, V, X, L, C, D, and M.
• Addition rule: When a smaller numeral is placed after a larger one, the values are added (VI = 5 + 1 = 6).
• Subtraction rule: When a smaller numeral is placed before a larger one, it is subtracted (IV = 5 - 1 = 4).
• Repetition rule: I, X, C, and M can be repeated up to three times in a row; however, V, L, and D are never repeated.
• Order rule: Roman numerals are generally written from left to right in descending order of value.
