Composing CXXXI in Roman Numerals

The composition of CXXXI in Roman numerals follows a specific process. By combining C, XXX, and I, we create CXXXI. The placement of C before XXX emphasizes the addition of 100 and 30, and the addition of I signifies the value of 1. Thus, CXXXI represents the desired value of 131.

Basic Rules for Writing Roman Numerals

  • The basic symbols in the Roman numeral system are I, V, X, L, C, D, and M, representing 1, 5, 10, 50, 100, 500, and 1000, respectively.
  • Symbols are combined to represent different values, with smaller-value symbols appearing to the right of larger-value symbols.
  • Symbols may be repeated up to three times in a row, except for four of the same symbol, which follows a subtractive notation (e.g., IV for 4) or nine of the same symbol (e.g., IX for 9).
  • When a smaller-value symbol appears before a larger-value symbol, it signifies subtraction. For example, IV represents 4 (1 subtracted from 5).
