* Five-step problem solving process. A five-step methodology for solving problems is used throughout the text. Each step is clearly identified to help students focus on the process of breaking a problem into smaller components and then addressing the smaller components throughout the text. The five steps are:
* State the problem clearly.
* Describe the input and the output.
* Work the problem by hand (or with a calculator) for a specific set of data.
* Develop a solution that is general in nature.
* Test the algorithm with a variety of data sets.
