500多张图片和表格展示了重要的概念
200多个模型示例，包含完整的解决方案
近1500个带答案的练习，因此你可以监控自己的进度
实用代数强调把你已经知道的和将来要学的联系起来。你将学习将代数视为一个逻辑一致的思想体系，并了解它如何与其他数学主题相联系。这本书把数学当作一门语言，使它更容易理解。它有发音和使用数学符号的技巧、代数常用术语表和符号表。一路上，你会发现数千年来世界各地不同的文化是如何发展出我们今天使用的许多数学思想的。由于现在的学生可以使用各种工具来处理复杂的建模任务，本书包含了适用于任何设备的技术提示。它还描述了避免学生犯常见错误的策略。
通过实践代数，你将学习解决问题的简单技巧，并理解这些技巧为什么有效，从而保留所学知识。你（或你的学生）会在代数考试中取得更好的成绩，并且对自己的数学能力更有信心。
Practical Algebra: A Self-Teaching Guide (Wiley Self-Teaching Guides), 3rd Edition
The most practical, complete, and accessible guide for understanding algebra
If you want to make sense of algebra, check out Practical Algebra: A Self-Teaching Guide. Written by two experienced classroom teachers, this Third Edition is completely revised to align with the Common Core Algebra I math standards used in many states. You’ll get an overview of solving linear and quadratic equations, using ratios and proportions, decoding word problems, graphing and interpreting functions, modeling the real world with statistics, and other concepts found in today’s algebra courses. This book also contains a brief review of pre-algebra topics, including arithmetic and fractions. It has concrete strategies that help diverse students to succeed, such as
over 500 images and tables that illustrate important concepts
over 200 model examples with complete solutions
almost 1,500 exercises with answers so you can monitor your progress
Practical Algebra emphasizes making connections to what you already know and what you’ll learn in the future. You’ll learn to see algebra as a logical and consistent system of ideas and see how it connects to other mathematical topics. This book makes math more accessible by treating it as a language. It has tips for pronouncing and using mathematical notation, a glossary of commonly used terms in algebra, and a glossary of symbols. Along the way, you’ll discover how different cultures around the world over thousands of years developed many of the mathematical ideas we use today. Since students nowadays can use a variety of tools to handle complex modeling tasks, this book contains technology tips that apply no matter what device you’re using. It also describes strategies for avoiding common mistakes that students make.
By working through Practical Algebra, you’ll learn straightforward techniques for solving problems, and understand why these techniques work so you’ll retain what you’ve learned. You (or your students) will come away with better scores on algebra tests and a greater confidence in your ability to do math.
