content: This book was the example used by my mathematical writing professor as how NOT to write math texts. The formatting is strange, the theorems and definitions are buried in the text with no delineation whatsoever. There are typos throughout the book, sometimes in the middle of proofs, making the proofs even more difficult to follow.The lack of exercises and examples are a little frustrating, as well, though this is typical of higher level math texts. I understand that the purpose of this book is to make analysis more accessible for undergraduates, but I feel that this book made the material more difficult than other, more advanced texts. Analysis is a challenging enough subject, and I feel that this book only exacerbates that.My personal recommendation to anybody starting an analysis course, undergrad or grad is Principles of Mathematical Analysis by Walter Rudin. It's more advanced but far more thorough and illustrative in its proofs.
