Simple Addition Subtraction

Cette application est spécialement conçu pour une simple addition et la soustraction de nombres.

This app is specially design for adding marks of papers where examiners or retotalling team needs to add most probably one digit marks.

In this app you are not required to press plus(+) or minus(-) sign after every digit. Due to eliminating plus or minus sign for every digit your work reduces more than 50%.

To change operation from addition to subtraction and vice versa we provided "+/-" button. Green color for this button indicate subtraction operation is in process and gray color indicate addition operation.

In this app user can add up to 29 using two extra buttons 10 and 20 for example if you want to add 17 you can use 10 and 7.

In general calculators you cannot add half marks directly (you have to press three buttons). It is very tedious task to remember halfs in adding marks. In our app you can add half marks with 0.5 button provided.

Round up of half marks facility is also provided in this app for that you can use "R" button.

Green color for this button indicate "Round Up" operation is in process and gray color indicate "Round Up" functionality is off.

Above addition result there is review text present which will show what digits you are adding.

You can delete wrong digits entered using "DEL" button.

You can see history of additions using menu provided in drawer and in option menu.
