This book emphasizes effective communication of mathematics through writing and it promotes active learning by the students. Notable features include preview activities for each section intended for students to do before class and progress checks within the text for the student to do on the spot, with answers at the end of the book.

Some exercises are “Evaluation of Proofs,” described in the preface:

For these exercises, there is a proposed proof of a proposition. However, the proposition may be true or may be false. If a proposition is false, the proposed proof is, of course, incorrect, and the student is asked to find the error in the proof and then provide a counterexample showing that the proposition is false. However, if the proposition is true, the proof may be incorrect or not well written. In keeping with the emphasis on writing, students are then asked to correct the proof and/or provide a well-written proof according to the guidelines established in the book.
