Can we add two Datafields of data type integer in a K2 blackpoint process. Add in the sense that if a Datafield has value 2 and other datafield has a value 3 then can we add both of these and store the resultant value 5 in a third datafield??

or

Otherways, can we increment a datafield as datafield++ or datafield = datafield + 1 like something in K2 blackpoint process??

Please Help.
