Answer 1

If I understand your question correctly, you want to just add a + or - sign along with the value a user puts in a form?

You can either add a hidden section to your form and put the value in and add that to whatever you want, or you can add it in server side.

Client Side Form

<input type="hidden" name="Sign" value="-">
