Query: worst math text ever

As a current grad student I have had the misfortune of encountering this book. This book is horrible even by math book standards. As others have said, it is poorly organized, doesn't explain the concepts well, doesn't actually teach how to go about solving problems, and examples skip too many steps. Every grad student has seen or heard these dreaded words: "(insert equation) can be solved easily to arrive at (insert completely different eqation minus the ten or twenty preceeding steps)" This book is filled with those instances. Professors, if you are caring enough to read this, care enough about your students NOT to get this book.
