Arithmetic on vB Variables?

[weinstoc]

Is there any way to treat a vB variable as a number and perform arithmetic on it?

If the forum id is 5 I would like to be able to write (in a template) something like:

$foruminfo[forumid]-2

and have it print out as 3.

How about:-

($foruminfo[forumid] - 2);

I did not think that I could put PHP code inside a template (say the footer)?

You have to write your PHP code in a plugin first then assign the result to a variable and use that variable in a template.
