ABSTRACT
We face problems of one type or another every day of our lives. Two-year-olds face the problem of how to climb out of their cot unaided. Teenagers face the problem of how to live on less pocket money than all their friends. Students have mathematics problems to do for homework. We have problems thinking what to have for dinner, how to organise a dinner party, what to buy Poppy for Christmas, how to fix the vacuum cleaner when it seems to have stopped sucking. Problems come in all shapes and sizes, from the small and simple to the large and complex, and from the small and complex to the large and simple. In some cases at least it is fairly obvious to those with experience what people should do to solve the problems. This book deals with what people actually do in their attempts to solve them.
