Key Principles for Writing Roman Numerals
Understanding the key principles for writing Roman numerals is important for correctly composing and interpreting them. Here are the principles to keep in mind when representing the number XCIX (99) in Roman numerals:
1. Addition: A larger numeral preceding a smaller numeral denotes their values being added together. For example, XC + IX = 90 + 9 = 99.
2. Subtraction: A smaller numeral before a larger numeral indicates that the smaller value is subtracted from the larger value. For instance, in the numeral IX, I (1) is subtracted from X (10) to form 9.
3. Repetition: A numeral can be repeated up to three times to represent the sum of its value. However, XCIX does not involve repetition, as it represents a specific value of 99.
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.
