# College Algebra, 1st Edition

## Description

Axler's College Algebra focuses on depth, not breadth of topics by exploring necessary topics in greater detail. Students will benefit from the straightforward definitions and plentiful examples of complex concepts.

The Student Solutions Manual is integrated at the end of every section. The proximity of the solutions encourages students to go back and read the main text as they are working through the problems and exercises. The inclusion of the manual also saves students money.

Axler's College Algebra is available with WileyPLUS; an innovative, research-based, online environment for effective teaching and learning.

• Depth, Not Breadth: Topics have been carefully selected to get at the heart of algebraic weakness by narrowing down to key sets of skills which are regularly revisited from varied perspectives.
• Exercises and Problems: The difference between an exercise and a problem is that each exercise has a unique correct answer that is a mathematical object such as a number or a function, while the solutions to problems consist of explanations or examples. The solutions to the odd-numbered exercises appear directly behind the relevant section.
• Variety: Exercises and problems in this book vary greatly in difficulty and purpose. Some exercises and problems are designed to hone algebraic manipulation skills; other exercises and problems are designed to push students to genuine understanding. Applications are written to reflect real scenarios, not artificial examples.
• Integrated Student's Solutions Manual: The solutions manual encourages students to read the main text and students will save money by not having to purchase a separate solutions manual.
• Designed To Be Read: The writing style and layout are meant to induce students to read and understand the material. Explanations are more plentiful than typically found in College Algebra books, with examples of concepts making the ideas concrete whenever possible.
• Calculator Problems: A symbol appears next to problems that require a calculator; some exercises and problems are designed to make students realize that by understanding the material, they can overcome the limitations of calculators.
