Calculate a sum (3)

Ross

I believe the answer is:

add

(Other definitions for add that I've seen before include "put two and two together" , "Go further" , "Count up" , "do some mathematics" , "what a computer can do" .)

I've seen this clue in the King Feature Syndicate, the Universal, the Newsday and the USA Today.
