Number Properties (1 of the 8 books in Manhattan GMAT's Preparation Guide series) provides a highly organized and structured approach to the variety of questions in this quantitative content area. Students are presented with a comprehensive analysis of the properties and rules of integers tested on the GMAT--everything from prime products to perfect squares. The book offers a unique balance between two competing emphases: test-taking strategies and in-depth content understanding. Practice problem sets build specific foundational skills in each topic and include the most advanced content that many other prep books ignore. As the average GMAT score required to gain admission to top b-schools continues to rise, this guide provides test takers with the depth and volume of advanced material essential for succeeding on the GMAT's computer adaptive format. Book also includes online access to 6 full-length Simulated Practice GMAT Exams at Manhattan GMAT's website.
This book is a quick and effective refresher of the mathematics commonly covered in middle school. I currently am tutoring two children in middle school math and so I have been regularly reviewing that specific content. Fundamentally the material being reviewed is basic number theory, exponents and roots. The general tactic is to put forward a short section of explanatory text followed by a set of related short problems and then detailed solutions. The fundamental assumption made by the creators is that you have seen it before, just need to be reminded in a challenging way. If you have a need to relearn the material covered in junior high math classes for any reason, this book is a good choice.
