XCI is not meaningless in Roman Numerals. It represents the number 91. In this numeral system, X stands for 10, C is 100, and I is 1. The combination XCI follows the convention of placing smaller numbers before larger ones to indicate subtraction; thus, 10 (X) is subtracted from 100 (C), making 90, and adding 1 (I) results in 91. Understanding Roman Numerals can be practical for reading clocks, book chapters, and historic dates.
