How Roman Numerals work?
The Roman numerical system combines 7 core letter glyphs: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). Additive rules combine characters left-to-right, while subtractive notation simplifies four consecutive letters (IV = 4, XL = 40, CM = 900).
Contemporary Usage
Roman numerals remain widely utilized in film copyright notices, clock dials, century numbering, monarchy titles, and major athletic tournaments.
