[mrtg] OID Math question

[Duncan Wallace]

I am trying to do some math here...What I want to do is add the two, divide
by two and subtract 4. So, (((temp1 + temp2) / 2) - 4) . Any clues, I have
tried the obvious.  Is there a delimiter I need to introduce to isolate the
operations ??? 


Thanks in advance
