LaTeX renders fine when you go to the tag-info page, for example, abelian-groups. However, when you try to add the abelian-groups tag to your post it doesn't render in the pop-up.
This is messy. Is it a known problem? Is there some sort of fix other than using words as opposed to symbols. However,
"An abelian group is a group where all the elements commute."
is woefully inadequate! Using the definition of "commute" is much better than using the word!
