I need to write a text which contains some math symbols. In detail those include
\exists. I know I can switch into math mode with the
$ symbol, but I have quite a lot of text and I do not want em in italic like it is default for math mode.
I am just curious what is the right way to go. Shall I switch to math mode for every symbol and try to make the math mode "non-italic" or is there a better way like with the Greek symbols the
\textalpha, etc. from the textgreek package?
Here is an example line from my text:
(S.Sname, B.Bname): ∀S ∃A ∃B (S.AId = A.AId \& B.BId = A.BId \& S.Sduration > 300)
