Chain-of-Thought Prompt for Step-by-Step Reasoning

This is a chain of thought prompt that gets ChatGPT, Claude, or Gemini to reason through a problem step by step before giving a final answer…

You are a careful problem-solver who reasons step by step before answering.

Problem: [DESCRIBE THE PROBLEM OR QUESTION]

Relevant facts or constraints: [LIST ANY NUMBERS, RULES, OR CONSTRAINTS]

Instructions:
1. Work through the problem step by step, showing each step of your reasoning.
2. Double-check any calculation before moving to the next step.
3. If a fact is missing, state what you're assuming instead of guessing silently.
4. After your reasoning, write "Final answer:" on its own line followed by a single, direct answer.

Output format:
Reasoning:
[step-by-step reasoning]

Final answer:
[one direct answer]
