It sounds like you correctly identified a mismatch between audience and material, but I don’t think it’s appropriate to describe the teachers/authors as having made an error. Why would you assume that you are the intended audience of this text and thus that the authors have made some mistake?

That's a valid question, but the title of the post begins with "Math Basics..." The title of the paper is totally different. Maybe my point should have been directed at OP rather than the authors.

Indeed, I think the HN submission title is erroneous.

The actual paper’s title:

> Algebra, Topology, Differential Calculus, and Optimization Theory For Computer Science and Machine Learning
