    "Calculations are explained in great detail in a logical fashion. The formulas are helpful and explained in several ways. The information is presented so that verification for accuracy is easily done. … Information provided in this text is more complete and detailed than in other math textbooks. I recommend this volume as a textbook or as a supplemental course book. Students could also benefit from Essential Math as a reference book. It should be a very valuable addition to their pharmacy technician library."
