Question 1

What are Roman numerals?

Accepted Answer

Roman numerals are a numeral system originating from ancient Rome that uses combinations of letters from the Latin alphabet: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). They are still used today for clock faces, movie sequels, and official documents.

Question 2

How do I read Roman numerals?

Accepted Answer

Add values when a smaller numeral follows a larger one (e.g. VI = 6). Subtract when a smaller numeral precedes a larger one (e.g. IV = 4). For example, MCMXCIX = 1000 + (1000-100) + (100-10) + (10-1) = 1999.

Question 3

What is the highest Roman numeral?

Accepted Answer

The standard Roman numeral system represents numbers up to 3999 (MMMCMXCIX). Higher numbers require a vinculum (overline) notation which extends the system, but this converter supports 1–3999.

Question 4

Accepted Answer

MMXXIV = 2000 + 24 = 2024. MM = 2000, XX = 20, IV = 4.
