Not adding numbers correctly!! – Krypto! Review

Believe me, I have played the card game and the online game; I know how to play. But this app is telling me my solution is incorrect, when a calculator backs me up. And the solution it gives is so off, I think they let a major programming error slip by their quality control. Needs critical work, if they want to sell the advanced version.
