The Roman numeral "XLIX" represents the number 49. In the Roman numeral system, "X" stands for 10, "L" stands for 50, and "I" stands for 1. The "XL" indicates 40, as it is a subtractive combination where "X" is subtracted from "L." The "IX" represents 9, where "I" is subtracted from "X." Therefore, when combined, XLIX equals 40 + 9, resulting in 49. Roman numerals, including XLIX, were widely used in ancient Rome for various purposes, such as numbering chapters in books, indicating the year of events, and marking clock faces. They are still used today in specific contexts, like the naming of Super Bowls and the numbering of movies in a franchise.
