Key Principles for Writing Roman Numerals
Understanding the key principles for writing Roman numerals is vital for correctly composing and interpreting them. Here are the principles to keep in mind when representing the number CXLV (145) in Roman numerals:
1. Addition: A larger numeral preceding a smaller numeral or a group of smaller numerals denotes their values being added together. For example, C + XL + V = 100 + 40 + 5 = 145.
2. Subtraction: A smaller numeral before a larger numeral indicates that the smaller value is subtracted from the larger value. However, CXLV does not involve subtraction as it directly represents the number 145.
3. Repetition: A numeral can be repeated up to three times to represent the sum of its value. But in the case of CXLV, there is no repetition of any numeral.
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.
