Learning to Reason: An Introduction to Logic, Sets, and Relations (047137122X) cover image
Learn how to develop your reasoning skills and how to write well-reasoned proofs

Learning to Reason shows you how to use the basic elements of mathematical language to develop highly sophisticated, logical reasoning skills. You'll get clear, concise, easy-to-follow instructions on the process of writing proofs, including the necessary reasoning techniques and syntax for constructing well-written arguments. Through in-depth coverage of logic, sets, and relations, Learning to Reason offers a meaningful, integrated view of modern mathematics, cuts through confusing terms and ideas, and provides a much-needed bridge to advanced work in mathematics as well as computer science. Original, inspiring, and designed for maximum comprehension, this remarkable book:
* Clearly explains how to write compound sentences in equivalent forms and use them in valid arguments
* Presents simple techniques on how to structure your thinking and writing to form well-reasoned proofs
* Reinforces these techniques through a survey of sets--the building blocks of mathematics
* Examines the fundamental types of relations, which is "where the action is" in mathematics
* Provides relevant examples and class-tested exercises designed to maximize the learning experience
* Includes a mind-building game/exercise space at www.wiley.com/products/subject/mathematics/
