    assuming that is in math mode (which you need already for \beta )that will work. What error do you get? – David Carlisle Nov 2 '16 at 7:50

    Please always post complete documents that allow people to reproduce the error and give exact error messages from the log. "not working" is not a useful description of the problem. – David Carlisle Nov 2 '16 at 7:51
  • @DavidCarlisle I posted a edit. – SirSaleh Nov 2 '16 at 8:27
  • Your edit does not help at all, you still haven't posted a document that would allow anyone to reproduce the problem, not have you said what error message you got. Also Answers should go in answer postings not by editing the question – David Carlisle Nov 2 '16 at 8:48

    No Idea why. but after adding two empty $ $ sign after this expression this works :| – SirSaleh Nov 2 '16 at 8:20

I don't know why, but after I added two dollar sign with just a space between that, the problem solved. and plus sign became subscript. This is what I did:

$$(\beta-\gamma)_{+}$$
$ $
