Frequently Asked Questions-

1. How do Roman numerals work?

   • Roman numerals are based on a combination of seven symbols: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). These symbols are combined to form numbers, using addition or subtraction rules. For example, IV represents 4 (5 - 1), and VIII represents 8 (5 + 3).

2. Can the Online Roman Numeral Converter handle very large numbers?

   • Most online converters can handle large numbers, but Roman numerals typically only go up to 3,999 in traditional formats (MMMCMXCIX). Some modern converters may also allow for larger numbers using additional notations like overlines or extended symbols.

3. What are the rules for Roman numeral conversion?

   • The primary rules include:
     • Symbols are added when written in descending order (e.g., VI = 6, VIII = 8).
     • Symbols are subtracted when written in ascending order (e.g., IV = 4, IX = 9).
     • The same symbol can only appear up to three times in a row (e.g., III = 3, but not IIII for 4).

4. What is the highest number that can be represented using Roman numerals?

   • Traditionally, Roman numerals could represent numbers up to 3,999 (MMMCMXCIX). However, modern variations of Roman numerals, such as those using overlines, can be used to represent larger numbers.

5. Why are Roman numerals still used today?

   • Roman numerals are used in various modern contexts like on clock faces, for movie or TV show sequences (e.g., "Rocky IV"), for outlining important events (e.g., Super Bowl numbers), and in legal or ceremonial purposes, giving a sense of formality or tradition.
