Question 1

How do Roman numerals work?

Accepted Answer

Roman numerals use seven symbols: I=1, V=5, X=10, L=50, C=100, D=500, M=1000. When a smaller numeral appears before a larger one, it is subtracted (IV=4, IX=9, XL=40, XC=90, CD=400, CM=900). Otherwise, values are added (VI=6, XI=11).

Question 2

What is the largest Roman numeral?

Accepted Answer

The standard system goes up to 3,999 (MMMCMXCIX). Numbers above 4,000 historically used a vinculum (overline bar) to multiply by 1,000, but this is rarely used today.

Question 3

What year is MMXXIV in Roman numerals?

Accepted Answer

MMXXIV = 2024. MM = 2000, XX = 20, IV = 4. Roman numerals are still commonly used in movie credits, clock faces, book chapters, and Super Bowl numbering.

Question 4

Why is 4 written as IV and not IIII?

Accepted Answer

IV uses the subtractive notation (5-1=4) which is the modern standard. However, IIII (additive notation) is also valid and is commonly seen on clock faces, known as the "watchmaker's four."
