The MRTG configuration reference on the web page show how to add two
values returned from SNMP together(MRTG arithmetic, which I already
knew). But, what I can't find is how excatly this works.

Say I am adding values like so..

Target[tot-internet]: at router
+ at router + at router + at router1

Does MRTG add the 4 values in front of the "&" together and the values
behind the "&" together and then graph the first sum as one value and
then the other sum as the other value??

Thanks for your time?
