About Roman Numerals
Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers in this system are represented by combinations of letters from the Latin alphabet.
The symbols are I, V, X, L, C, D, and M, standing respectively for 1, 5, 10, 50, 100, 500, and 1,000. Numbers are formed by combining these symbols and adding the values, with certain rules for subtractive notation (e.g., IV for 4, IX for 9).
- Basic Symbols: I, V, X, L, C, D, M
- Values: 1, 5, 10, 50, 100, 500, 1000 respectively
