About this title

Synopsis

"Such a pleasure. A unique and wonderful book!" Imre Leader, Professor of Pure Mathematics, University of Cambridge.

Ashley starts listing numbers 1, 2, 3, 4, 6, 8, 9, 10, ..., missing out every number containing a digit 5 or 7. What is the 1000th number in his list?

This is not an ordinary puzzle book. Beautifully crafted and immensely enjoyable, the problems require minimal technical knowledge, being accessible to young secondary school pupils. However, there is an astonishing range in difficulty; while some of the problems are fairly straightforward, others are significantly tougher, with a great deal of ingenuity and clarity of thought needed to make progress.

Whether you are

• a student preparing for a maths competition,
• an educational establishment seeking to supplement your problem solving resources, or
• an individual looking for a different sort of challenge,

Elastic Numbers is a unique collection, and will push you to the very edge of your abilities.
