Basic Rules to Interpret Roman Numerals Basic Symbols: Roman numerals are composed of basic symbols to represent the: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). Repeated Symbols: If a Roman numeral has a symbol repeated, the values are added together. For example, II is 1 + 1 = 2, and XXX is 10 + 10 + 10 = 30. Subtractive Notation: When a smaller Roman numeral appears before a larger one, it is subtracted from the larger one.For example, IV represents 5 – 1 = 4, and IX represents 10 – 1 = 9. No More Than Three Repeats: A Roman numeral cannot have more than three consecutive identical symbols. To represent larger numbers, subtractive notation is used. For example, 4 is IV (one less than 5), not IIII. Order of Symbols: Roman numerals are read from left to right, and symbols are combined according to the rules above. Larger values should always come before smaller ones. For example, 98 is written as XC (10 before 100, with a subtraction). Successive symbols cannot increase in value by more than tenfold. For example, 99 is not IC (100 – 1) but XCIX (10 before 100, 1 before 10, and 10 before 1). Like Article Suggest improvement Next How to Write 500 in Roman Numerals?
