 New, more challenging problem sets to allow instructors greater flexibility in choosing which problems to assign students for particular topics.
 Problem sets and exposition in Chapter 4 Use Matrix Logic, Chapter 8 Analyze the Units, Chapter 12 Draw Venn Diagrams have been revised to make the material more clear, readable, and concise.
 More illustrative examples have been added to better explain to students how to use particular problemsolving strategies.
 An improved text design and layout boldly calls out section heads and explanations in order to make the text more readable and studentfriendly.
 Examples are solved as dialogues between fictitious students so students can see common errors and learn to avoid pitfalls.
 Each chapter includes relevant examples of the strategy presented.
 Chapters conclude with problem sets made up of three levels: A (routine), B (lengthy), and Classic Problems whose level can be determined by instructors.
 Over a dozen distinct problemsolving strategies are developed in depth, including classic strategies as well as more contemporary strategies.
 Icons appear to indicate examples, important information, and difficult material.
