All about Roman Numerals
Roman numerals are letters that stand for numbers. The main ones are I = 1, V = 5, X = 10, L = 50, C = 100, D = 500 and M = 1,000. They were used across the Roman Empire and are still seen on clocks, book chapters and films.
Roman numerals are usually written from largest to smallest and added together, so VI = 6 and XV = 15. When a smaller value comes before a larger one, you subtract it, as in IV = 4 and IX = 9.
