This book is aimed at those who want to improve their numeracy and arithmetic skills. It presents a wide range of techniques to simplify numerical calculations (to the point where many can be performed mentally without writing down any working). As well as describing these techniques, this book promotes a different way of approaching arithmetic problems than the traditional one taught in most schools. Specifically, the book promotes the idea that it is better to learn a wide range of techniques to solve a problem, (each technique optimised for a particular problem type), rather than learn just one general purpose technique to solve all problems in a particular class. Learning multiple techniques may initially seem like more work, but it will be seen that most of these techniques are very simple, making many seemingly difficult problems much easier to solve (by taking advantage of specific properties that are not present in the general case). Perhaps even more important than the more efficient arithmetic techniques is the deeper understanding gained by being aware of multiple approaches to the solution of any particular problem.

|I found this book in what looked like an abandoned state, (hardly any content and no recent edits). I could not find any similar book on the subject so I started filling it out. There is still a long way to go on this one, any help would be appreciated. GandalfUK (talk) 10:00, 29 April 2010 (UTC)
