Key Principles for Writing Roman Numerals
Understanding the key principles for writing Roman numerals is crucial to correctly compose and interpret them. Here are the principles to keep in mind when representing the number XL (40) in Roman numerals:
Addition: The larger numeral X (10) precedes the smaller numeral L (50), indicating their values are added together. XL represents 10 + 50 = 40.
Subtraction: When a smaller numeral appears before a larger numeral, it signifies subtraction. However, XL does not involve subtraction as it represents a direct value of 40.
Repetition: A numeral can be repeated up to three times to represent the sum of its value. For example, III represents 1 + 1 + 1 = 3. However, XL does not involve repetition as it represents a specific value of 40.
Limit on Repeating: A numeral should not be repeated more than three times consecutively. For example, 4 is represented as IV (5 - 1), not IIII.
