Overview
A short paragraph framing what the chapter is about and why it matters — the one thing a reader should walk away understanding. Keep it to a few sentences.
Key ideas
The heart of the summary. Walk through the chapter’s main moves in plain language. A statement is a sentence that is either true or false — never both, never neither. “Paso Robles is in California” is a statement. “Close the door” is not, and neither is “What time is it?”
Introduce terms in bold the first time they appear, and lean on short, concrete examples rather than abstract definitions.
Worked example
Show one idea being applied, start to finish — the kind of thing the book walked through so the reader sees the mechanics, not just the rule.
Try it
Where the book had you work an exercise by hand, drop in a widget. This one is a placeholder until the interactive pieces are built (see the authoring guide), but it already renders as a styled, self-contained card:
Takeaways
Close with the one- or two-sentence version a reader should remember: a statement is a claim with a truth value, and logic is the study of how those truth values combine.
