Roman numerals, often seen in old clocks or historical documents, use letters like I, V, X, L, C, D, M to represent numeric values. For example, IX means 9 (10 – 1), and XVI means 16 (10 + 5 + 1). Generally, if a smaller numeral precedes a larger one, you subtract; otherwise, you add. So MCMLXXXIV is 1984. By learning these rules—like I=1, V=5, X=10, L=50, C=100, D=500, M=1000—you can decode centuries-old texts, interpret monument inscriptions, or even style modern events. Converting Roman numerals fosters a deeper appreciation of number systems and historical contexts.
