Explain a concept in plain language
Explaining an idea to an imagined beginner can expose gaps hidden by technical vocabulary. The explanation still needs checking: sounding simple is not the same as being accurate.

A worked example
Try explaining compound interest. “Interest can earn interest” is a start, but an example makes the mechanism clearer. With a hypothetical 10% annual rate, 100 becomes 110 after one year and 121 after the second if nothing is added or removed. State those assumptions; real products can have different rates, fees and rules.
Try it in three steps
- Choose one concept.
- Give a small example with stated assumptions.
- Check missing details and revise the explanation.
What to watch for
An analogy usually has limits. Record where the comparison breaks down instead of stretching it to explain everything.
Apply it to your own material
Choose one topic from your current course or project. Write down the question you want to answer, make an attempt, and keep a note of how you checked it. Use the example above as a pattern; replace its subject matter and assumptions rather than copying an answer into a different task.
