Why Is 69 Unique in Roman Numerals?
Roman numerals, while simple in structure, can sometimes be counterintuitive:
- Subtractive Notation: The use of smaller letters before larger ones to indicate subtraction can be confusing. For example, IX means 10-1, not 10+1.
- Positional Value: Unlike the Arabic system, the value of Roman numerals does not depend on their position, but this can still lead to misunderstandings.
<p class="pro-note">✅ Pro Tip: When reading Roman numerals, remember that when a smaller numeral precedes a larger one, it indicates subtraction, like 'IV' for 4.</p>

Common Mistakes to Avoid
When dealing with Roman numerals, several common errors can trip you up:
