From the reviews: "The book ... is a problem book in real analysis, chosen mostly from mathematical Olympiads and from problem journals. ... The book focuses on analysis on the real line, which is also known as advanced real calculus. ... the book under review is a collection of interesting and fresh problems with detailed solutions. The target audience seems to be students preparing for Olympiads and other competitions, but undergraduate students, mathematics teachers and professors of Mathematical Analysis and Calculus courses may also find interesting things here." (Mehdi Hassani, The Mathematical Association of America, August, 2009) "In this book, the authors intend 'to build a bridge between ordinary high-school or undergraduate exercises and more difficult and abstract concepts or problems' in mathematical analysis. ... The book may readily be used as a self-study text or ... as a classroom text. The introductory material in each section is reasonably self-contained and includes interesting examples and applications. ... the collection is a very worth-while contribution and should be included in every high school, college, and university mathematics library collection."
