To compute, print this sum in any calculator and get the answer - without thinking.

It is the fastest way "to compute" literally, without wasting your time.

Another deal, if you want to say "Simplify, then compute" instead of "Compute".

If you want the people understand you correctly, use correct words in your posts.
