Why does my calculator?
I have an iphone 6 on iOS 8.2. and when i typed in 108000-540000. The answer turns into 0 and not 540000. My friend's iphone 5s on iOS 8.2 also does the same thing. Is there an update that can fix that?
No update is required. You are tapping the - (minus) sign twice, once after entering the first number, then again at the end.
