This is a small (98 page) textbook designed
to teach mathematics and computer science students the basics of how
to read and construct proofs.
Why
do students take the instruction "prove" in examinations to
mean "go to the next question"?
Because
they have not been shown the simple techniques of how to do it. Mathematicians
meanwhile generate a mystique of proof, as if it requires an inborn
and unteachable genius. True, creating research-level proofs does require
talent; but reading and understanding the proof that the square of an
even number is even is within the capacity of most mortals.
Proof in Mathematics: an Introduction
takes a straightforward, no nonsense approach to explaining the core
technique of mathematics.
"Mathematics teaches you
to think" is often an empty marketing slogan. With this book, it
can become a reality.
Contents:
1. Proof
2. "All" statements
3. "If and only if" statements
4. "Some" statements
5. Multiple quantifiers
6. "Not", contradiction and counterexample
7. Sets
8. Proof by mathematical induction

Praise for the first edition:
(Introduction to Proofs in Mathematics, Prentice Hall, 1988)
"Delightfully written ..."
Mathematics Teacher
(USA) 82 (Dec 1989)
"does not cloud the issue
with a sea of philosophical niceties, instead it takes a pragmatic approach
that should prove appealing to students. The language is easy to read
and stimulating for a student of average ability... This pragmatic and
essentially elementary book on the nature of proof is A definite step
in the right direction."
Mathematical
Gazette (UK) 73 (Oct 1989)
"should help students enormously
in their appreciation of what mathematics is all about ... one cannot
help being affected by the obvious enthusiasm of the authors, which
I feel certain will be conveyed to students."
Australian Math
Soc Gazette 15 (5) (Oct 1988)
"The style is lucid and stimulating
and does not oblige the reader to read through unnecessary padding ...
without presenting this fundamental idea [proof] in mathematics can
the accusation be made that students of mathematics are not being well
taught?"
Australian Mathematics
Teacher 46 (3) (1990).
"can be warmly recommended
especially to first-year university students and their teachers."

The book has been used successfully
for 14 years in the first year Discrete Mathematics courses at the University
of New South Wales.
