Both "something++"  and or "something--" are just changing "something".  In 
your described cases, by one.

But you can write "something++" differently.  Like "something += 1" or even 
"something = something + 1".   All three wil work (try it!).

And with any assignment you can put whole calculations at the right of the 
"=" (like "anything = anything / 2 + 1"), or even expressions which calls 
other functions and/or methods.    Which is what happens in your case.

Hope that helps.
