## A PGML WeBWorK Sample Problem

*This sample problem illustrates the basics of how to use PGML commands to layout a question.*

This sample just scratches the surface of what is possible using these mark up commands. Page through the sample questions to see what can be done and click on the "show problem source" button to see how to accomplish it.

As usual a standard WeBWorK PG file has five sections:

- A
*tagging and description section*, that describes the problem for future users and authors, - An
*initialization section*, that loads required macros for the problem, - A
*problem set-up section*that sets variables specific to the problem, - A
*text section*, that gives the text that is shown to the student, and - OPTIONAL --An
*answer*, that specifies how the answer(s) to the problem is(are) marked for correctness, and gives a solution that may be shown to the student after the problem set is complete. As you will see this section can be used but are not necessary when using PGML commands. - A solution section

The sample file attached to this page shows this; below the file is shown to the left, with a second column on its right that explains the different parts of the problem that are indicated above.

This is the The description is provided to give a quick summary of the problem so that someone reading it later knows what it does without having to read through all of the problem code.
All of the tagging information exists to allow the problem to be easily indexed. Because this is a sample problem there isn't a textbook per se, and we've used some default tagging values. There is an on-line
list of current chapter and section names and a similar
list of keywords, as well as a page of best practices for tagging problems. The list of keywords should be comma separated and quoted (e.g., |
