Key Principles for Writing Roman Numerals
Understanding the key principles for writing Roman numerals is essential for correctly composing and interpreting them. Here are the principles to keep in mind when representing the number XC (90) in Roman numerals:
1. Addition: A larger numeral preceding a smaller numeral denotes their values being added together. However, XC involves subtraction, not addition.
2. Subtraction: A smaller numeral before a larger numeral signifies the smaller value subtracted from the larger value. In the case of XC, X (10) is subtracted from C (100), resulting in 100 - 10 = 90.
3. Repetition: A numeral can be repeated up to three times to represent the sum of its value. However, XC does not involve repetition, as it represents a specific value of 90.
4. 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.
