This is a short English draft for the Chinese article “从卷积到反演：莫比乌斯反演在做什么”. The full translation is not finished yet, but this page is enough to verify the bilingual blog flow.

This draft keeps only a short English opening for the algorithm topic. The complete derivations, formulas, and code snippets are still in the Chinese version.
Continue with the Chinese version if you want the complete notes, examples, proofs, and code snippets.
