Key Principles for Writing Roman Numerals
Understanding the key principles for writing Roman numerals is crucial for composing and comprehending them. Here are some key principles to keep in mind:
- A larger letter preceding a smaller letter means their values are added together. For example, VIII (8) is written as V + I + I + I = 5 + 1 + 1 + 1.
- A smaller letter preceding a larger letter indicates that the smaller value is subtracted from the larger value. For example, IX (9) is written as X - I = 10 - 1.
- A letter can be repeated up to three times to represent the sum of its value. For example, III (3) represents 1 + 1 + 1.
- A letter should not be repeated more than three times in succession. Instead, subtractive notation is used for numbers such as 4 (IV) and 9 (IX).
