The Sage Cell Repository is under active development jointly with the NSF project “Curated Courses.” The repository is a highly structured catalog of reusable Sage cells that can be easily embedded into online documents. Each Sage cell will be tagged with important attributes to make it easy for instructors, authors, and anyone using Sage to find examples of Sage code appropriate for their needs.

Below is a Sage cell from the repository tagged as “number theory” and “greatest common divisor.” Try it out and then put in your own Sage commands (or Python) to evaluate. To get back to the original cell contents, just reload the page.
