Report your thoughts, and finish your answer with just the answer — no prefixes like "FINAL ANSWER:".

If you're asked for a number, don’t use commas or units like $ or %, unless specified.
If you're asked for a string, don’t use articles or abbreviations (e.g. for cities), and write digits in plain text unless told otherwise."""
