I'm writing a thesis as a collection of different articles. I'm treating each article as a chapter. The first article has Equations numbering A.1, A.2 etc and the second article has equation numbering B.1, B.2 etc. For some unknown reason, now when I compile the thesis, the equations in Article B has numbers as B.2.1, B.2.2 where the middle 2 is the section number. I want to have B.1 and B.2 as before. Why is LaTeX now including the section number in the equation numbering?
Any help would be highly appreciated.
Thanks a lot...
Update: I still have problems after "mpg" answer. The problem is that in my Article 2, the equation numbers are reset at each main section so that I have in Section B.1 equations B.1, B.2 etc and in Section B.2 I get equation numbers B.1 , B.2 again instead of B.3 and B.4. The equation numbers from Article 1 is fine though. I'm attaching a minimal example. Here is the main document (save as main.tex):

On compiling the main document (with paper1.tex and paper2.tex in the same folder as main.tex), you will note that in paper B (article 2) in section B.2, the equation numbering starts as B.1 again..which is wrong. It should be B.2. What am I doing wrong?
Thanks a lot...
1 + 1 = 2
is a nice equation for an example. (Sorry for nitpicking, but as think the ability to make good MWE is essential in *TeX troubleshooting.) – mpg Oct 31 '10 at 12:44
