✅ How to use this effectively
- 1. Paste the prompt into the chat.
- 2. Enter chapter, class, and board.
- 3. Send and read the mistakes column.
- 4. Ask for an example of any mistake.
- 5. Print for class discussion.
🔧 If it is not right, reply with this: If a mistake feels invented, reply: "Replace the mistake for formula [number] with a realistic, frequent student error, and verify the correct formula."
THE PROMPT
ROLE: Act as a mathematics teacher who pairs every formula with the trap students fall into.
CONTEXT: I teach [CLASS/GRADE] for the [BOARD or EXAM e.g. CBSE / ICSE / State Board / JEE / NEET]. I want a formula sheet for [CHAPTER NAME] where each formula is shown with the SINGLE most common mistake students make when using it, plus how to avoid it.
YOUR TASK:
1. List each key formula of the chapter in textbook order.
2. For each, state the most common, realistic mistake students make (misapplied condition, wrong sign, wrong variable, forgotten factor).
3. Give a one-line 'how to avoid it' fix.
4. Keep it scannable - formula, mistake, fix, on tight lines.
INPUT: Here is the chapter and class. Chapter: [PASTE HERE]. Class/Board: [PASTE HERE].
HOW TO WORK IT OUT: For each entry, internally confirm the formula is correct and the stated mistake is a genuine, frequent error - not a contrived one. VERIFY two ways: (a) re-check each formula for accuracy; (b) ask 'do students really make this exact mistake?' and replace any weak ones. Never invent a formula or a fake mistake. Keep all maths fully legible in clean plain text or simple LaTeX.
OUTPUT FORMAT (use this exact order):
1. TITLE: '[Chapter] - Formulas with Common Mistakes (Class [X], [Board])'.
2. 'Compiled by [YOUR NAME]'.
3. A numbered list. For each: 'Formula:' line, 'Common mistake:' line, 'How to avoid:' line.
4. A short 'Top 5 mistakes overall' summary box.
5. Footer line.
RULES: Mistakes must be realistic and frequent. Formulas must be correct. Fixes must be actionable. No padding.
OUTPUT FILE FORMAT: present the complete result as a clean, ready-to-use document I can paste straight into Microsoft Word or Google Docs - a clear bold title, section headings, neatly numbered items, comfortable spacing, and simple tables only where helpful (avoid heavy formatting that breaks on paste). It must also print cleanly to PDF on A4 (File > Print > Save as PDF). Keep all mathematics fully readable (fractions as a/b, powers as x^2, roots as sqrt(x)).
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.
