This review is from: Intermediate Algebra (with CD-ROM and Printed Access Card Enhanced iLrn(TM) Math Tutorial, iLrn(TM) Math Tutorial, The Learning Equation Labs, Student Resource Center) (Paperback)
One of the first things that jumps out at the reader of this text book is the colour - I remember algebra texts from nearly three decades ago when I first learned the subject, and they were usually fairly boring black-and-white texts. This has colour on every page. There are marginal pull-quote boxes that explain in simpler, verbal language some of the algebraic and mathematical concepts being demonstrated in the problems. There are also marginal notes that give hints (Success Tips, Caution, and Notation pieces) to remind students of key concepts or introduce important and special elements.
Each chapter begins with a new chapter opener, introducing in broad strokes the content of each chapter. This is also keyed to TLE (The Learning Equation) labs that are part of the internet components to this text. The text also includes a CD-ROM supplement for students. Each chapter includes worked examples in great detail, self-check problems and strategy/property boxes that give short explanations of the key concepts in the worked examples.
The progression of topics in the text is familiar to those who know algebra:
Chapter 1 is a review, including review of numbers, basic equations and variables. Chapter 2 begins the introduction of simple lines and graphs, including graphs of functions. The third chapter looks as systems of equations and how to solve them in different methods, including algebra, matrices and determinants. The fourth chapter introduces inequalities, including compound inequalities and absolute value issues.
From chapter five forward are issues of exponents, polynomials, rational equations, radical equations, quadratic equations and attendant issues. These include issues of factoring, dividing, geometric applications, and introduces imaginary and complex numbers.
The final three chapters explore exponential and logarithmic functions (very useful in science), conic sections (two-dimensional analytic geometry), and some theoretical considerations for algebra, especially of interest to those going on to higher math. These include some elemtns of interest to those who will need statistics, too.
The preface includes some study tips for students to follow, which are very important. This is a checklist worthwhile for students in any math class (and can be adapted for students in any other class, too).
Algebra is the kind of subject that few can master on their own without classroom or tutorial instruction; I have yet to meet the textbook that will teach algebra to everyone without teaching assistance, and this book is no different. But as a classroom book, and as a book we use in our Tutoring Center, this is a very useful, helpful and clearly written text.
