5. How Roman Numerals Work: A Mini Tutorial

Roman numerals are built on seven symbols:

• I (1), V (5), X (10), L (50), C (100), D (500), M (1,000)

Rules:

• Additive notation: Placing larger values first (e.g. XII = 12): 10 + 1 + 1.
• Subtractive notation: A smaller symbol before a larger subtracts (IV = 4; IX = 9)
• Limits on repetition: Most symbols repeat up to three times (e.g. XXX = 30); longer counts use subtractive forms.
• Overlines: Denote thousands, like _V = 5,000

These conventions emerged over centuries, mixing additive and subtractive notation since Roman and Etruscan times, refined as Arabic numerals entered Europe

7. Real-World Example: Chronicle Translation

I once worked on digitizing a library collection. One chimney bore “MDCCLXXIV”—a quick conversion gave me 1774. Another foundation plaque displayed _X_C_C representing 110,000—a subtle detail, but crucial for accurate digitization. Without a converter, these readings might have skewed century records by hundreds of years.
