"A fascinating collection of interesting things"
- Kaye Stacey, Professor of Mathematics Education, University of Melbourne.
"This new book, as well as being a delightful read, is of immense value to both teachers and students. The author has succeeded in presenting a comprehensive range of techniques in a very readable, thorough and jargon-free manner."
- Charlie Watson, The Tuition Centre, Perth.
"Problems, puzzles and proofs are intermingled with explanation and advice, and the book avoids excessive formality, adopting a light, even humorous, tone throughout. It is an engaging resource, with plenty to interest any young mathematician and much for any mathematics teacher to delve into. Enjoy!"
- Colin Foster, Association of Teachers of Mathematics. http://www.atm.org.uk/reviews/
"Proof is superb! Some features I especially enjoyed: Conversations about proof; identities and proof; sprinkler on the lawn example (neat!); the future of proof; many continuations of a series; proof projects; the proof that ab is rational for some irrational a and b. I am sure that it ought to be very successful in the classroom."
- David Wells, author of many popular mathematics books, including You are a mathematician and Curious and interesting numbers.
"The IB maths course gives significant weight to mathematical proof, so why not set Diploma Programme students to work on a collection of puzzles and projects around the subject? Dr Paul Brown's 'classroom-proven' book is a great introduction to the real world of mathematics."
