Update screwed me :-( – RLM-Fin-CX Review

This app used to be 5 stars... Until the most recent update. It went from Reverse Polish Notation to BROKE. RPN involves the following sequence: 25 [Enter] 2 [X], which produces the result of 50. After the update, RPN is no longer functional. Please fix ASAP!
