🔢 Roman Numeral Basics

Before solving:
- I = 1, V = 5, X = 10, L = 50, etc.
- When a smaller numeral appears before a larger one, it's subtracted (e.g., IV = 4, IX = 9).
- Otherwise, values are added (e.g., VI = 6, XV = 15).

🧠 How to Solve These Step-by-Step

#### Example: IX - V
- IX = 9 (since I before X means 10 - 1 = 9)
- V = 5
- 9 - 5 = 4 → IV

#### Example: XV - III
- XV = 15 (10 + 5)
- III = 3
- 15 - 3 = 12 → XII (10 + 2)

#### Example: IV + X
- IV = 4
- X = 10
- 4 + 10 = 14 → XIV (10 + 4)
