Hi all, I'm producing one of my first proper TeX documents and getting a strange effect. A couple of my equations have the equation numbers stuffed onto the end of the equation virtually adjacent to it, rather than on the right hand side aligned with all the other labels. Any ideas why? I think it might have something to do with an error regarding brackets within the equation. Both the offending equations contain brackets ( ) , and TeX doesn't seem to be recognising that one closes the other. I'm working in TeXnicCenter using MikiTeX if that's relevant, and usually clicking on a closed bracket highlights it in green along with its partner; but these brackets both appear as open brackets (highlighted pink-ish alone when you click on them). Thanks in advance.
