Sage is an open source, online symbolic mathematical system. Details on Sage can be found at http://www.sagemath.org .
For use within WebWork, a special "single-cell" version of Sage is located at http://sagecell.sagemath.org

The example shows how to pass perl variables from the problem initialization into the sage block.
- TEXT(<<SAGE_CODE);
where << SAGE_CODE without single quotes is necessary. However, the Sage code will not execute if no variables are actually passed in. Since $ and @ within the Sage code are now interpreted by perl, all latex delimiters should be converted from $ signs to \ ( and \ ) pairs. Additionally, any @interact needs to be escaped and written as ~~@interact
If you are not passing any variables, use:
- TEXT(<<'SAGE_CODE');
where <<'SAGE_CODE' tells perl not to interpret variables. Sage code can then be pasted in verbatim without any need to convert formatting or escaping other characters.
