How do you count in Roman numerals? - Answers

Roman numerals use certain characters to represent different values. The first three are: I = 1, V = 5, X = 10 If you place more than one of a character in a row, you add them together. For example: I = 1, II = 1 + 1 = 2, III = 1 + 1 + 1 = 3 Note that you can't have more than 3 of a given character in a row. So IIII would not work. If you place a smaller character after a larger character then you add them as well. For example: V = 5, VI = 5 + 1 = 6, VII = 5 + 1 + 1 = 7, VIII = 5 + 1 + 1 + 1 = 8 Note again that VIIII would not work because you can only use a character three times in a row. If a smaller character comes before a larger character then you subtract. For example: V = 5, IV = 5 - 1 = 4, X = 10, IX = 10 - 1 = 9 So the first 20 numbers in roman numerals from 1 to 20 are: I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV, XVI, XVII, XVIII, XIX, XX
