Roman Numerals Chart for Students
Roman numerals use letters to represent numbers. They are still seen on clocks, book chapters, outlines, movies, and historic dates.
Key ideas
- I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, and M = 1,000.
- When a smaller symbol comes before a larger symbol, subtract it.
- IV means 4 because 1 is before 5.
- XIV means 14 because X is 10 and IV is 4.
