The discussion centers on the book "Calculus: The Elements" by Michael Comenetz, which is aimed at undergraduate students with a prerequisite knowledge of high school mathematics. The author previously wrote a prepublication review praising the book, but notes that its price has significantly increased since then. There is a consideration of the book as a potential alternative text for Calculus III. A key concern raised is whether the book is accessible for students who have a solid understanding of typical Calculus I and II topics, specifically regarding the clarity of its language and the need for external guidance from professors to understand the material.
