didn't we used to get the percentage calculated shown when calculating percentages in the app?
Example: 100 + 10% would already show that the resulting percentage calculated in this case was 10.
You would get (I think) 100 + 10% = a line with 10 and then the result 110.
Now it just shows you 100 + 10% = 110.
For easy numbers this is fine but for complex numbers you have to do a additional steps and subtract the original number from the result to show the calculated percentage.
Complex example:
(European formatting - sorry my American friends

).
374.829+37,9847% = 517.206,671163 -> then I have to do "- 374.829" = 142.377,671163 to find how much the percentage calculated as a number was.
But if you type the "-/minus" your original calculation input is then removed and you have to look up the number again on your paper or something or go to the history to look it up and memorize it. (or am I doing something wrong)?
This is very inefficient.
Oh and I know that on your casio 100 - 10% is not the same because Apple does interpretations of this calculation for you. (100 - 10% = 99,9)
