Learning to Reason 
An Introduction to Logic, Sets, and Relations

Learn how to develop your reasoning skills and how to writewell-reasoned proofs

Learning to Reason shows you how to use the basic elements ofmathematical language to develop highly sophisticated, logicalreasoning skills. You’ll get clear, concise, easy-to-followinstructions on the process of writing proofs, including thenecessary reasoning techniques and syntax for constructingwell-written arguments. Through in-depth coverage of logic, sets, and relations, Learning to Reason offers a meaningful, integratedview of modern mathematics, cuts through confusing terms and ideas, and provides a much-needed bridge to advanced work in mathematicsas well as computer science. Original, inspiring, and designed formaximum comprehension, this remarkable book:

* Clearly explains how to write compound sentences in equivalentforms and use them in valid arguments

* Presents simple techniques on how to structure your thinking andwriting to form well-reasoned proofs

* Reinforces these techniques through a survey of sets–thebuilding blocks of mathematics

* Examines the fundamental types of relations, which is ‘where theaction is’ in mathematics

* Provides relevant examples and class-tested exercises designed tomaximize the learning experience

* Includes a mind-building game/exercise space atwww.wiley.com/products/subject/mathematics/
