Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Numerous errors

Besides copious amounts of unnecessary jargon and run-on sentences, the listed solutions (both in the appendix and separate [$$$] solutions manual) for problems in this book are frequently incorrect. BIG INCONVENIENCE AND WHOLLY UNACCEPTABLE; given that few problems in linear algebra are quickly processed by hand. If you use this text, expect to spend an hour on one problem attempting to find errors in your approach when in fact there are none, and the listed solution was just wrong.Instructors and students agree that the frequency of incorrect answers is the biggest problem with this text.Thou art warned.
