I purchased this book with the intention of preparing for a Real Analysis course I had planned to enroll in. While many of my acquaintances recommended "Book of Proof" by Richard Hammack, which is generously available for free, I found this particular book to be exceptional. It goes beyond merely presenting proofs; it teaches you how to approach the process of proving something. The author emphasizes the importance of "scratch work" in developing your proof-writing skills. Additionally, I appreciate the author's inclusion of helpful tips and tricks at the end of each chapter, as well as thought-provoking open questions in the field. The book even provides a glimpse into more advanced topics related to each chapter. Moreover, the author's use of witty and pun-filled footnotes-feetnote as the author would like to call it- adds an entertaining aspect to the reading experience. I absolutely love it!
