This book covers all of the major areas of a standard introductory course on mathematical rigor/proof, such as logic (including truth tables) proof techniques (including contrapositive proof, proof by contradiction, mathematical induction, etc.),... read more

The text is very suitable for an "introduction to proofs/transitions" course. I have used this book as the primary text for such a course twice, a course with two main goals: prepare the student for proof-centric classes like abstract algebra and... read more

This textbook covers an excellent choice of topics for an introductory course in mathematical proofs and reasoning. The book starts with the basics of set theory, logic and truth tables, and counting. Then, the book moves on to standard proof... read more

I use this book for a "Discrete Mathematics for Educators" course. The students are all prospective middle and high school teachers, and the main goals are to prepare them for upper level mathematics courses involving proofs, and to give them a... read more

## About the Book

This is a book about how to prove theorems.

Until this point in your education, you may have regarded mathematics primarily as a computational discipline. You have learned to solveequations, compute derivatives and integrals, multiply matrices and finddeterminants; and you have seen how these things can answer practicalquestions about the real world. In this setting, your primary goal in usingmathematics has been to compute answers.

But there is another approach to mathematics that is more theoreticalthan computational. In this approach, the primary goal is to understandmathematical structures, to prove mathematical statements, and evento invent or discover new mathematical theorems and theories. Themathematical techniques and procedures that you have learned and usedup until now have their origins in this theoretical side of mathematics. Forexample, in computing the area under a curve, you use the fundamentaltheorem of calculus. It is because this theorem is true that your answeris correct. However, in your calculus class you were probably far moreconcerned with how that theorem could be applied than in understandingwhy it is true. But how do we know it is true? How can we convinceourselves or others of its validity? Questions of this nature belong to thetheoretical realm of mathematics. This book is an introduction to that realm.

This book will initiate you into an esoteric world. You will learn andapply the methods of thought that mathematicians use to verify theorems,explore mathematical truth and create new mathematical theories. Thiswill prepare you for advanced mathematics courses, for you will be betterable to understand proofs, write your own proofs and think critically andinquisitively about mathematics.
