Understanding Roman Numeral Rules:
Additive Principle: When a smaller numeral precedes a larger one, you add the values together. For example, II is 1 + 1 = 2, and VI is 5 + 1 = 6.
Subtractive Principle: When a smaller numeral comes before a larger one, you subtract its value. For instance, IV is 5 - 1 = 4, and IX is 10 - 1 = 9.
Repetition Principle: A numeral can be repeated up to three times to increase its value. For example, III is 1 + 1 + 1 = 3, and XXX is 10 + 10 + 10 = 30.
