A Course of Pure Mathematics by G. H. Hardy is meant to be an introduction to math that has no direct applications. Although people with interest in such things as engineering can gain something from this book, they are not the primary intended audience. Since it is a “Course” in Pure Mathematics, this book contains plenty of examples and exercises. However, since it is also for a student, it doesn’t show you the answers to the exercises, or at least I have not found them.
Since this book is before calculators it also has a lot of interesting things about it, like the Root Extraction formula and other stuff like that. As the blurb on the back mentions, this book mostly covers mathematics that utilizes the notion of the limit. So Calculus topics are covered in here. The table of contents goes further in depth into what you might find if you just want to skim it.
All in all, this book was quite well done, with this edition being a reprint of the tenth edition.
