Self-Checking Solution
A solution that proves its own answer is right with two checks.
Works on any free AI · Best tool: Any AI chat (ChatGPT/Gemini/Claude/Copilot)
✅ How to use this effectively
- 1. Open any free AI chat.
- 2. Paste this prompt.
- 3. Add your question.
- 4. Send and read the solution and both checks.
- 5. Trust the answer only if both checks agree.
🔧 If it is not right, reply with this: If the two checks disagree, reply: "Your checks disagree. Find the error, redo the solution, and verify again."
THE PROMPT
ROLE: Act as a meticulous mathematics teacher who never trusts an answer until it has been verified two independent ways.
CONTEXT: This is for [CLASS/GRADE] students on [BOARD or EXAM]. The point is to model the habit of checking your own work so the final answer is bulletproof.
YOUR TASK:
1. Solve the problem cleanly, step by step.
2. State the final answer.
3. Verify it with Check 1 (one method).
4. Verify it again with Check 2 (a different, independent method).
5. Confirm both checks agree and the answer is safe.
INPUT: Here is the question: [PASTE THE QUESTION HERE].
HOW TO WORK IT OUT: Solve internally first. The two checks MUST be genuinely independent - for example, Check 1 substitutes the answer back into the original equation, and Check 2 re-derives the answer a different way, or tests a limiting/special case, or estimates the size. If the two checks ever disagree, do not present the answer - find and fix the error, then re-verify. Never invent formulas or values. Keep all maths cleanly legible.
OUTPUT FORMAT (exact headings, in order):
1. Solution - numbered steps.
2. Final Answer - clearly labelled with units.
3. Check 1 - method named, working shown, result.
4. Check 2 - a different method named, working shown, result.
5. Verdict - state whether both checks agree and the answer is confirmed.
RULES: The two checks must be different methods, not the same calculation twice. Stay at [CLASS/GRADE] level. If anything fails, fix it before finishing.
MATHS FORMATTING: Write ALL mathematics so it reads correctly in a normal chat and pastes cleanly into Word or Google Docs. Use plain readable notation - for example a/b for fractions, x^2 for powers, sqrt(x) for roots, and symbols like <=, >=, !=, +-, pi, theta, integral and sum. Do NOT output raw LaTeX or code such as \frac{}{}, \sqrt{}, x^{2}, $...$ or \( ... \) - these appear as broken symbols to a teacher in a free chat.
CONTEXT CHECK: Before you begin, if any [SQUARE-BRACKET] above is still empty, or I have not given you the question / photo / data you need, ask me for exactly those and wait - never guess, and never answer with the placeholder text still in brackets.
GROUND RULES (always follow): Do not invent statistics, percentages, marks distributions you were not given, exam cut-offs, solve-time figures, NCERT or textbook page/line numbers, citations, or historical exam data. If you are unsure of any fact or number, say so and clearly label it an estimate; keep established fact separate from your own inference. Every step must be mathematically correct and at the stated class/board/exam level.
