I was recently using my iPhone 5S to calculate grades for students on a test. Overall total points were 120 and I would subtract 42 points from 120 and my calculator would give me 77 each time. I cannot understand why it gave me this answer 3 times in a row. Anyone else having the same problem? Also how can I contact Apple so they know their calculator isn't functioning correctly?

With all due respect, it is far more likely you are inadvertently tapping the wrong numbers that it is the calculator app is randomly giving you the wrong results, particularly with a function that simple. But ... I'm not looking over your shoulder. You can report issues to Apple here: http://www.apple.com/feedback/
I get 78. Are these are the exact numbers you are inputting, or are you calculating other inputs to get tot 120?
Yep, I get 78 also.
I just tried it 20 times. Both clearing after the calculation and not clearing. 78 every time. Maybe you are hitting the 3 instead of 2 when entering 42?
Sometimes I get 78, but I have also gotten 77 three straight times. Those are the exact numbers I am inputting. I do not add anything to get to 120, or 42.
calculator continually gives wrong calculation
