Question 1

What is the range of Roman numerals?

Standard Roman numerals represent integers from 1 to 3999. The symbols are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).

Question 2

How does subtractive notation work?

Accepted Answer

A smaller numeral placed before a larger one is subtracted: IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900. This avoids repeating a symbol four times.
