[jQuery] putting value to html from a php script

[Rotsen]

I am new to this group and JQuery.  I am reading a lot of stuff about
it but I nee to ask a question for something that I to create.
I have an area in my html page where I want to call a php script that
prints a total.
Is it as simple as this:
   $.get("totals.php" );

Am I  in the rigth track?

Thanks,

Nestor :-)
