If you have the time, patience, and the inclination to get a strong introduction to Calculus then this book will probably meet your needs.  Note I say 'probably' because for many of the young folks today the text may seem wordy and overly pedantic.  Kline forfeits the graphical techniques of learning for the verbal.  So one has to carefully follow the explanations.  Later in the book graphical explanations for things like differentiation are explained.<br><br>So if you expect a fast paced text like say 'Calculus for Dummies', 'How to Ace Calculus' etc you will be disappointed.  What I found helps is to get going with some modern quickie texts like Dummies etc and then go with Kline's work.  This helps firm up some theory instead of just learning the mechanical stuff.  Also, as others have pointed out, but this needs to be mentioned, the answers to problems can be obtained via a PDF from Dover.  They answered my email promptly.<br><br>If you want a good reference for introductory Calculus without say the rigor of Apostol's text this is a great investment that should serve you for years to come.  Excellent textbook.
