## Complete Problem Authoring Templates by Subject Area

This page has complete examples of problem templates organized by subject area. Within each subject, we give an explicit and brief description of the essential characteristics of each type of question. To keep overlap to a minimum, we try to give an example of each problem technique exactly once, which means you may need to look for a particular problem technique under other subject headings until you find it. We try to give a fairly complete list of techniques, rather than a complete list of types of questions that one might ask in each subject. All of these questions exist in the National Problem Library (NPL) at `NationalProblemLibrary/FortLewis/Authoring/Templates/`

A detailed list of code snippets for specific problem techniques has it's own category: index of problem techniques.
