I don't know what kind of explanation you seek here.
Here is an example. 0 + 0 + 0 + 1 + 1 + 1 = 3. Subtract from 7, and
you get 4. If you want to check this out directly with Stata, use
-display-.
Also, to find out what the -egen- function -rowtotal()- does, look in
the help for -egen- explanation. The name -rowtotal()- is in fact
indicative, meaning "row total" across a varlist.
Alternatively, if you didn't want what these calculations do, please
revise your question.
