Learn a concept through a worked example
Connect an idea to a concrete scenario, with explicit assumptions, visible calculation or implementation steps and a practice problem.
What to provide
- A concept and scenario with the values needed to work through it.
Example Illustrative example
Input
Illustrative editorial example — not a recorded model test. Concept: total cost from quantity, unit price and a fixed fee. Scenario: four notebooks at 3.50 each plus a fixed delivery fee of 2; no other charges.
Output
Assumption: the delivery fee applies once and there are no other charges. Item cost = 4 × 3.50 = 14. Total = 14 + 2 = 16. The fixed fee is added once, after multiplying the unit price by quantity. Practice: What is the total for six notebooks at 3.50 each with the same delivery fee?
Improve the result
- Check each intermediate step and then give the answer to the practice problem with the same assumptions.
How to use this prompt
Provide actual values and state what is excluded from the example. Ask for each intermediate step so you can locate an error instead of receiving only a final answer.
What to check in the result
An apparently plausible worked example can contain arithmetic or implementation errors. Check calculations independently and run code in an appropriate test environment.
