Mathematical Ideas By: Miller, Heeren, Hornsby Price: new $102.00 (Expanded 9th edition) The Expanded 9th Edition contains: Problem Solving Set Theory Logic Numeration and Mathematical Systems Number Theory Real Numbers Algebra Graphs and Functions Systems of Equations and Inequalities Geometry Counting Methods Probability Statistics Consumer Mathematics Graph Theory Voting and Apportionment Pros: This textbook is designed primarily for education majors and so this book is less terse and easily understandable compared to some other general mathematics textbooks. It contains basic information about a variety of mathematical topics, making it ideal for a person who wishes to be well-rounded in general mathematics. Plenty of practice problems provide sufficient exercises for the mathematical mind. Every other page or so, the authors provide a biographical sketch of a famous mathematician or an interesting note about notation or history. Cons: Because it is designed primarily for education majors, it lacks the depth that other mathematical textbooks have. Overall: I would highly recommend this book for anybody interested in learning the basics of mathematics.
