# Roman numerals → integer

Use this skill when the user asks you to convert a Roman numeral (e.g., `XIV`, `MCMXCIV`) into a base-10 integer.

## Output format

Return only the integer as decimal digits (no extra words or punctuation).

## Procedure

1. Map symbols to values: `I=1`, `V=5`, `X=10`, `L=50`, `C=100`, `D=500`, `M=1000`.
2. Walk left to right:
   - If a symbol is followed by a larger symbol, subtract it.
   - Otherwise, add it.
3. Sum to get the final integer.
