About the Author Marge Lial Marge Lial was always interested in math; it was her favorite subject in the first grade! Marge's intense desire to educate both her students and herself has inspired the writing of numerous best-selling textbooks. Marge, who received Bachelor's and Master's degrees from California State University at Sacramento, is now affiliated with American River College.Marge is an avid reader and traveler. Her travel experiences often find their way into her books as applications, exercise sets, and feature sets. She is particularly interested in archeology. Trips to various digs and ruin sites have produced some fascinating problems for her textbooks involving such topics as the building of Mayan pyramids and the acoustics of ancient ball courts in the Yucatan.John Hornsby When John Hornsby enrolled as an undergraduate at Louisiana State University, he was uncertain whether he wanted to study mathematics, education, or journalism. His ultimate decision was to become a teacher, but after twenty-five years of teaching at the high school and university levels and ten years of writing mathematics textbooks, both of his goals have been realized. His love for teaching and for mathematics is evident in his passion for working with students and fellow teachers as well. His specific professional interests are recreational mathematics, mathematics history, and incorporating graphing calculators into the curriculum.John's personal life is busy as he devotes time to his family (wife Gwen, and sons Chris, Jack, and Josh). He has been a rabid baseball fan all of his life. John's other hobbies include numismatics (the study of coins) and record collecting. He loves the music of the 1960s and has an extensive collection of the recorded works of Frankie Valli and the Four Seasons.Terry McGinnis - A native Midwesterner, Terry received her Bachelor's of Science in Elementary Education (Mathematics concentration) from Iowa State University. She has taught elementary and middle school mathematics, and developed and implemented the curriculum used with her students. Terry has been involved in college mathematics publishing for over 15 years, working with a variety of authors on textbooks in developmental and precalculus mathematics. After working behind the scenes on many of the Lial/Hornsby textbooks and supplements for the past ten years, Terry most recently joined Margaret Lial and John Hornsby as co-author of their developmental mathematics series that includes Introductory Algebra, Intermediate Algebra, and Introductory and Intermediate Algebra, all published by Addison-Wesley. When not working, Terry enjoys spinning at a local health club and walking. She is a devoted parent of two sons, Andrew and Tyler. --This text refers to the Hardcover edition.

说实话,我本来以为这本号称覆盖“初级和中级”的教材,在中级内容上会显得仓促或浮于表面。但事实完全出乎我的意料。当我翻到关于解二次方程那一章时,作者简直是将不同的解题方法——从因式分解到配方法,再到万能的求根公式——做了一场精彩的“方法论大比拼”。他不仅教会了我们每种方法的具体步骤,更重要的是,他分析了每种方法的适用范围、效率以及在概念上的优势与劣势。例如,他会指出在某些特定结构下,使用配方法能更好地展示方程的几何意义,而求根公式则提供了最快的数值解。这种多维度的分析,极大地提升了我解决问题的策略性思维。这本书的作者似乎深谙“授人以渔”的真谛,他不仅仅是在传授知识点,更是在培养一种成熟的数学家应有的批判性思维和问题解决路径选择能力。对于那些希望真正从“做题机器”转变为“思考者”的读者来说,这本书提供了必要的思维工具箱。
评分我必须得提到这本书的实用性和参考价值,这绝对是它作为一本工具书的最高体现。很多教材在学习完后就束之高阁了,但这本书,我发现自己时不时还会翻阅回去查阅细节。它的附录部分做得堪称完美,里面集合了所有重要的代数性质、特殊公式速查表,甚至还有一些常见符号的解释。我曾经为了一个关于分数指数的性质疑惑了很久,翻阅市面上其他资料都没找到满意的解释,最后在这本书的附录里找到了一个非常简洁明了的图表总结,瞬间就解决了我的困惑。此外,这本书的语言风格非常注重精确性与可读性的平衡。它在保持学术严谨度的同时,避免了过度使用晦涩的术语,使得即便是多年未接触数学的成年人,也能快速重新进入学习状态。总而言之,这不是一本“一次性”读完就束之高阁的书籍,而是一本可以伴随你走过代数学习旅程,并且在未来需要巩固基础时随时可以信赖的“案头宝典”。
评分这本书的排版和设计简直是业界良心,打开它就像是进入了一个为学习者精心打造的舒适空间。我通常看数学书会觉得眼睛很累,但这本书的字体大小和行间距拿捏得恰到好处,即便是长时间阅读也不会感到疲惫。更棒的是,它在关键概念的呈现上非常注重视觉引导。那些需要特别强调的定理和公式,都会用醒目的彩色框或者粗体字突出显示,而不是简单地用黑白文字堆砌。我特别喜欢它在每章末尾设置的“概念回顾”和“常见误区警示”部分,这简直是救命稻草!很多时候,我以为自己理解了,但回顾清单一看,才发现自己对某个小细节存在盲区。它不会直接告诉你“你错了”,而是用一种启发式的提问引导你去重新审视自己的理解。这种“你来找答案”的互动方式,极大地增强了我的主动学习能力。对于自学成才的人来说,这本书的结构设计简直是教科书级别的典范,它让你感觉自己不是一个人在战斗,而有一个经验丰富的导师在旁边默默支持。
评分天呐,我刚刚读完一本让我爱不释手的数学书,简直是为我这种数学“小白”量身定做的!我一直对代数望而却步,觉得那些复杂的公式和符号就像是天书一样。然而,这本书的叙述方式简直是太亲切了,它不是那种冷冰冰的教科书,更像是邻家那位耐心又幽默的数学高手在手把手教你。书中的例子总是贴近生活,让你能立刻明白那些抽象的概念在现实世界中到底意味着什么。比如,讲解变量和方程时,它会用一个买东西的场景来举例,那种豁然开朗的感觉,真的太美妙了。而且,它的习题设计也十分巧妙,从基础的加减乘除,到稍微复杂一点的二次方程,难度是循序渐进的,每当你觉得自己快要掌握的时候,它会适时地抛出一个更有挑战性的题目,让你保持专注和兴奋。最让我感动的是,作者似乎完全理解初学者在哪个知识点上会卡住,然后在那些关键的转折点上,会用好几页篇幅来反复强调、用不同的方式解释,直到你彻底搞懂为止。这本书让我对数学重拾了信心,感觉自己真的可以掌握代数这门学科了。
评分我对这本书的逻辑结构和内容覆盖面的深度感到非常震撼。它绝不仅仅是一本“入门级”的读物,而是真正实现了“入门到进阶”的完美过渡。初期的内容打磨得非常扎实,对基础概念的定义清晰到几乎不容置喙,这为后续更复杂的学习打下了极其坚实的地基。当我们进入到中级代数的部分,比如多项式运算和函数图像分析时,作者的处理方式显得尤为老练。他没有急于引入高深的理论,而是巧妙地通过实际应用场景,比如优化问题或者增长率的计算,来自然地引出新的数学工具。我记得在讲解函数变换时,作者用了动画般生动的语言来描述图像如何“平移”和“拉伸”,那种画面感让我瞬间就记住了规则,而不是死记硬背公式。这本书的伟大之处在于,它真正做到了让读者理解“为什么”要这么做,而不是仅仅告诉你“怎么做”。这种对数学思维深层逻辑的挖掘和展示,是市面上很多代数书所欠缺的,使得学习过程充满了智力上的愉悦感。
