Frequently Asked Questions
What is the valid range?
1 to 3999 - standard Roman numerals have no symbol for zero or for numbers of 4000 and above.
Why do some numerals subtract, like IV for 4?
It's subtractive notation: a smaller symbol before a larger one means subtract it, avoiding four repeated symbols in a row (IIII).
