Query: I Wouldn't Even Use This Book to Start a Fire

Lawson's textbook is absolutely terrible. The book provides hardly any examples, and the few examples it does provide make giant leaps in calculations and steps. In addition to the two supplementary manuals to this textbook, Lawson should have another manual devoted solely to apologies for the Math department's monopolistic imposition of this textbook.
