To provide professors and students of mathematics with a useful, free, beginning Numerical Analysis textbook, this book was written.

This book's ultimate objective is to be a comprehensive, single-semester, downloadable textbook for math classes that is available in PDF format.

In Tea Time Numerical Analysis, current events are generally covered. The book begins with an introductory chapter, then moves on to chapters on root-finding techniques, interpolation (part 1), numerical calculus, and interpolation (part 2), with a chapter on differential equations being added in the second edition.

This book's programming language, GNU Octave, was chosen in order to create an entirely free learning environment.
