Frequently Asked Questions

What are the 7 standard Roman numeral symbols?

The seven symbols are: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).

Why is 4 written as IV instead of IIII?

Roman numerals use subtractive notation to prevent more than three identical symbols consecutively. Placing I before V subtracts 1 from 5 to yield 4.

Does zero exist in Roman numerals?

No, ancient Romans had no symbol for zero. They used the Latin word "nulla" when indicating nothingness.
