Preface
It is with pleasure that we offer the eleventh edition of Beginning Algebra. With each
new edition, the text has been shaped and adapted to meet the changing needs of both
students and educators, and this edition faithfully continues that process. As always,
we have taken special care to respond to the specific suggestions of users and re-
viewers through enhanced discussions, new and updated examples and exercises,
helpful features, updated figures and graphs, and an extensive package of supple-
ments and study aids. We believe the result is an easy-to-use, comprehensive text that
is the best edition yet.
Students who have never studied algebra—as well as those who require further review
of basic algebraic concepts before taking additional courses in mathematics, busi-
ness, science, nursing, or other fields—will benefit from the text’s student-oriented
approach. Of particular interest to students and instructors will be the Study
Skills activities and Now Try Exercises.
This text is part of a series that also includes the following books:
NIntermediate Algebra,Eleventh Edition, by Lial, Hornsby, and McGinnis
NBeginning and Intermediate Algebra, Fifth Edition, by Lial, Hornsby, and
McGinnis
NAlgebra for College Students,Seventh Edition, by Lial, Hornsby, and McGinnis
In this edition of the text, we are pleased to offer the following new student-oriented
features:
Study SkillsPoor study skills are a major reason why students do not succeed in
mathematics. In these short activities, we provide helpful information, tips, and
strategies on a variety of essential study skills, including Reading Your Math Text-
book, Tackling Your Homework, Taking Math Tests,andManaging Your Time.While
most of the activities are concentrated in the early chapters of the text, each has been
designed independently to allow flexible use with individuals or small groups of stu-
dents, or as a source of material for in-class discussions. (See pages 48 and 163.)
Now Try ExercisesTo actively engage students in the learning process, we now
include a parallel margin exercise juxtaposed with each numbered example. These all-
new exercises enable students to immediately apply and reinforce the concepts and
skills presented in the corresponding examples. Answers are conveniently located on
the same page so students can quickly check their results. (See pages 3 and 87.)
Revised Exposition As each section of the text was being revised, we paid special
attention to the exposition, which has been tightened and polished. (See Section 1.
Real Numbers and the Number Line, for example.) We believe this has improved dis-
cussions and presentations of topics.
