"Mathematical thinking is not the same as 'doing math'--unless you are a professional mathematician. For most people, 'doing math' means the application of procedures and symbolic manipulations. Mathematical thinking, in contrast, is what the name reflects, a way of thinking about things in the world that humans have developed over three thousand years. It does not have to be about mathematics at all, which means that many people can benefit from learning this powerful way of thinking, not just mathematicians and scientists."--Back cover.

Answers, Hints and Solutions have been provided to boost up the morale and increase the confidence level.Self Assessment Sheets have been given at the end of each chapter tohelp the students to assess and evaluate their understanding of the concepts.
