The defintive guide to mathemathical problem solving from one of the great teachers of the twentieth century How to Solve It offers something unique- a tried and tested set of strategies for overcoming any maths dilemma. Based on decades of analysis of the methods and rules of problem solving and invention, acclaimed mathematician George P lya's approach brilliantly demonstrates how to create useful analogies, tackle problems from unusual angles and how to squeeze a little more information from the data. While maths can often seem nothing more than a process of dry deduction, P lya wonderfully conveys the challenge and excitement at the heart of any problem, and lays out the blueprint for unpicking the riddles they pose. With more than a million copies sold around the world, How to Solve It has inspired generations of teachers and students to look afresh at maths - and continues to be the definitive guide to mathematical problem solving.
