अक्सर पूछे जाने वाले प्रश्न
Why do Roman numerals still exist?
Roman numerals appear in formal documents, clocks, book chapters, and movie copyright dates. They're recognized as elegant formal notation.
How do I know if a numeral like IV is subtraction?
When a smaller value appears before a larger value, it's subtraction: IV=4, IX=9. When larger is first, it's addition: VI=6, XI=11.
