I was doing some quick math for my quiz, and this is where things got really messed up for me.
So, when you calculate 34+112+90+110+67+228+177+145+53+77+227+11+48+90+38+202+188+70+102+21+169+137+63+122+31, you get the answer of 2612. Any normal or scientific calculator will give you that number, but somehow, the samsung calculator gave me the wrong answer of 2552. It's kind of weird, but the app managed to give me a difference of 60, which doesn't really make sense in this situation.
If you try the same summation, you should get 2612, but if you also got 2552, join the club.
2612
@CoFe: I checked this on the Calculator app, and using the Google Calculator, and both produced the sum of 2,552. Very strange, indeed.
EDIT: Tried again and got 2,612. Asked my colleagues to try, and they all unanimously got 2,612.
I can see that, in your screen shot, you have entered '117' after '228', instead of '177'. This accounts for the missing 60.
