In this app you are not required to press plus(+) sign after every digit. Due to eliminating plus sign your work reduces to 50%.
In this app user can add upto 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. It is very tedious task to remember halfs in adding marks. In our app you can add half marks with 0.5 button provided. It will round up half marks.
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.
With "H" button you can see history of additions.
In upcoming updates we will provide voice recognised addition. In which you need not to press buttons only read marks loudly and your addition will be ready. We are also working on image recognised addition of marks (question wise) of front page so that you need not to worry about wrong total of marks.
