# Preview eats first and last $so ignores displaystyle The preview appears to be eating the first and last dollarsigns in double dollarsigned expressions hence causing displaystyle expressions to be ignored, e.g. see here • sorry, I'm not following -- I don't know MathJax very well. I don't see any meaningful difference between your post, pasted in as a preview, and the final rendered post? Note that we auto-escape everything between $..\$ now though, so it should be untouched. – Jeff Atwood Nov 13 '10 at 19:51

• @Jeff: It's not as glaringly obvious now since that post has been subsequently edited. But all double-dollar displaystyled LaTeX forms are now left-justified instead of centered in the preview pane. – Bill Dubuque Nov 13 '10 at 21:16
• @Jeff Atwood: I posted an example as an answer to this report. – Tsuyoshi Ito Nov 13 '10 at 22:11

Example: The following equation is enclosed as $$…$$ and therefore centered in the actual answer.
$$x=1.$$
