HTML doesn't provide such a facility, the reliable way to achieve such a
thing is to provide a form with two input elements of type text, and one of
type submit.
http://www.w3.org/TR/html4/interact/forms.html
Then write a form handler in the server side language of your choice to
perform the addition. The specifics of such depend on the capabilities of
your server. http://www.cgi101.com/learn/ gives a basic introduction to the
principles of writing CGI scripts in Perl.
You could also look at client side JavaScript, but it is bad practise to
depend on it and it should usually only be considered as a convenience to
the user (e.g. to duplicate work that a server side program is already in
place to perform).
