# How do I put a linebreak in a displaymath? [duplicate]

How can I split an equation over two lines

I have a `displaymath` formula that's too long. `\linebreak` and other commands that work in inline math don't seem to do anything. Is there any way to break the `displaymath` onto multiple lines? (or preferably, have latex break it automatically?)

I saw some other related questions here at tex.stackexchange, which said "use `align`/`eqnarray*`/etc instead". My formula doesn't need breaking for layout reasons, just because it's too long, so I'd prefer to keep using `displaymath`. Is there a way to linebreak without changing environments?

• I recommend not insisting on using the single-line math environment `displaymath` for multiple lines. amsmath offers simple multi line environments such as `multline` and `gather` but also more sophisticated. – Stefan Kottwitz Aug 11 '11 at 14:38
