About Math Explained

Math Explained is an independent explainer site. Each article takes one established topic, from algebra and geometry through calculus, and walks through the reasoning step by step so readers can follow why a method works, not only what to compute. Accuracy comes first, and the standard facts are the ones found in ordinary textbooks.

The author is not a formal authority, and mistakes happen. If you spot an error, an unclear step, or a result that does not check out, corrections are welcome. Point to the article and the line, and the post will be reviewed and fixed.
