What is opportunity cost in economics?

In economics, opportunity cost refers to the value of the next best alternative given up when a choice is made. It matters because the same idea reappears across many later topics, so building a clear mental picture of it early saves a lot of time.

How to approach it step by step

To work with opportunity cost confidently, list the alternatives, then value only the best one forgone. LetMeTeach draws this out live on screen while explaining it aloud, so you watch each part appear instead of decoding a static block of text. You can interrupt at any point and ask for the same idea again in simpler words, in another language, or with a different example.
