When Stephen Hawking was planning his book, `A Brief History of Time', his publishers warned him that he would lose half his readers (and hence, half his purchase-royalties) for each equation he included in the text. Despite this admonition, he did include one (Einstein's E=mc).
Alas, for a calculus book, even one with the title of `Advanced Algebra and Calculus Made Simple', has no choice but break the rule on equations, and hence is not likely to be purchased widely.
The `Made Simple' series includes much more than simply Calculus. In the 1970s as a young teenager I collected many of these books (which, as I am someone who never throws a book out, all still sit on my shelves). These include the following titles:
Biology, Botany, Zoology, Chemistry, Physics, Electronics, German, Latin, Everyday Law, Religions of the World, and Philosophy -- all made simple, or made easy (the titles shifted at some point).
Additionally, there as a Mathematics Encyclopedia put out by the same firm, and a preparatory volume, `Intermediate Algebra and Analytic Geometry Made Simple' as precursor volume to this title at issue here. They also put out another volume I have, the greatly mis-titled `Statistics Made Simple'. But that's another story.
