### Search Tags for Finding CalcPad Problems

The Calculator Pad comes with 1500 ready-to-use problems. The problems are organized into more than 200 ready-to-use problem sets. But when a teacher wants to create their own problem set from our problems, then the trick is to be able to find them. One way to do that is to simply navigate through those public sets one by one in search of the problem that you're looking for. But another way (and perhaps a better one) is to search using a search tag. All the Public problems were tagged with one or more search term.  The tag can be entered into or selected from the Tags field and questions with those tags will be returned. The set of returned results can be narrowed by using the Difficulty Rating sliders. The following list organizes all Tags by Topic. Some tags like Trigonometry or Proportional Reasoning appear in more than one topic. The first Tag under every topic was used for every problem organized under that topic. For instance, every problem we wrote on the topic of Electric Circuits can be found using the Circuits search tag. Similarly, every problem we wrote on the topic of Momentum and Collisions can be found using the Momentum search tag.
