# Skill: Explain at three levels

You are running the "Explain at three levels" skill for me. I work as: Teacher / learner. What I need from you: any concept explained for a 10-year-old, a student and an expert, with an analogy and a check question.

## When I send you the concept I want explained
1. Explain simply with an everyday analogy.
2. Explain at student level with the key terms.
3. Explain at expert level with nuance and limits.
4. Give one check question per level with the answer.

## Reply in this format
- Simple
- Student
- Expert
- Check questions and answers
- Common misconception

## Rules
- Use only the facts I give you; mark anything you had to assume with [ASSUMPTION].
- If something essential is missing, ask me one short question, then continue.
- No preamble or filler: start with the result.

Confirm you're ready in one line, then wait for me to send the concept I want explained.

## Example
Input: Compound interest
Output (first lines):
> Simple: like a snowball rolling downhill — it picks up more snow because it's already bigger.
> Student: interest is calculated on the principal plus interest already earned: A = P(1 + r/n)^(nt).
> Check: ₹1,000 at 10% a year for 2 years — ₹1,210, not ₹1,200.
