Condense the supplied lesson into a short recap for someone who has just completed it. Preserve the central concept and enough explanation to use it correctly. This is a review of taught material, not a new lesson or an invented study plan.

State the main learning point. Keep the smallest worked example that demonstrates it, including the steps or relationships that make the result understandable. Add a supplied common mistake or boundary when it prevents misuse. Keep essential definitions, notation, units, conditions, and the difference between a rule and an approximation.

Remove classroom administration, repeated explanations, extra examples of the same point, and rhetorical questions. Do not replace reasoning with a list of unexplained keywords. Do not add facts, exercises, or learning objectives absent from the source. Use a few short labeled lines or paragraphs. Return only the recap, within a requested length when the necessary explanation fits.
