《Intermediate algebra》摘要

"Intermediate Algebra" by Margaret L. Lial is a comprehensive textbook designed for students transitioning from basic mathematics to more advanced mathematical concepts. The book focuses on essential algebraic principles, incorporating a mix of theory, application, and real-world problem-solving techniques. Lial structures the content through a clear, logical progression, facilitating learners to build a solid foundation in algebra. One of the distinctive frameworks of this book is its emphasis on the exploration of functions, particularly linear, quadratic, and polynomial. Each chapter provides a thorough examination of these functions, offering various representations such as tables, graphs, and equations. The text also emphasizes the importance of solving equations and inequalities, where students work with an array of algebraic techniques including factoring, completing the square, and utilizing the quadratic formula. The book is organized into numerous chapters, each focusing on specific themes and concepts such as rational expressions, radicals, and systems of equations. Lial incorporates practical applications and technology throughout, encouraging students to utilize graphing calculators and software to assist in their understanding. Additionally, real-life applications are demonstrated in examples that relate to everyday situations, enhancing the relevance of the material. Beyond merely presenting formulas and rules, "Intermediate Algebra" contains numerous exercises that challenge students to think critically and independently. Its design is particularly conducive to self-paced learning, equipped with numerous practice problems and cumulative reviews at the end of each chapter that reinforce the understanding of complex topics. Overall, Lial's "Intermediate Algebra" serves as a crucial springboard for students preparing for higher-level mathematics by effectively blending theory with application.
