# Include the cancel package for LaTeX

In explaining derivations and proofs, it is really handy to show terms that go to zero or cancel with each other.

Is it possible to include the cancel package or something equivalent in the MathJax install?

• I'm not sure if the SE team supports adding additional LaTeX packages to the MathJax installation. (If they do, cancel would be just one of a long list of packages that would be useful to us.) – David Z Mar 3 '11 at 7:01
• @David: Of course you're right. It would have to be done by the SE team and would be useful in their other sites. I put the question here as a single item wishlist! – Simon Mar 3 '11 at 7:15
• @Robert: Thanks for the thread. So it would be comparatively simple to add a basic strikethrough to the MathJax setup... – Simon Mar 3 '11 at 7:16
• @David, @Simon. This kind of stuff wouldn't be done by the SE team but by the MathJax team. They already said that 'cancel' is in the pipeline. – Robert Smith Mar 3 '11 at 15:35
• Thanks @Robert, that's good to know. – Simon Mar 3 '11 at 21:40
• Use \not. It's esp. imp. in like Feyn. slash not. etc. – Abhimanyu Pallavi Sudhir Aug 4 '13 at 13:45
