G. Polya "How to Solve It"

"What is the unknown? What are the data? What is the condition?"

The reason I read it was that our textbook for software seminar said, "At one time, Microsoft gave this book to all its new programmers."(Steve McConnell Code Complete)
When we solve a mathematical question, we tend to lose our way. We always have to understand what to do, in short "What is the unknown?". We have to know what we have, or "What are the data?". Then we link the unknown to the data, i.e. "What is the condition?".
Polya is a mathematician. But The ideas in this book can apply to any problem. When we face a problem, we have to devide it and change it to solve.
