Professor Bard has provided a valuable service by carefully explaining everything an undergraduate student of mathematics, or a teacher of these topics, needs to get started with Sage quickly and easily. It will also be useful for any student or teacher of another STEM discipline. There is an excellent mix of the most frequently used commands, along with warnings about common pitfalls or caveats. I highly recommend it for anyone new to Sage, or who desires an overview of the system's impressive capabilities." - Robert A. Beezer, University of Puget Sound, USA "This book is a sort of 'Missing Manual' that explains how Sage can be used in a range of standard mathematics courses, instead of targeting specialists like much existing Sage documentation. The depth of content is very impressive, and describes - in a single coherent narrative - how to successfully use Sage for a wide swath of undergraduate applied topics." - William Stein, University of Washington, Seattle, USA
