## The main &kpercentage; window

In the main window you can only enter one of the three input boxes. Here you have to type in your guess. Press Enter or click the Apply Button, to see if you are right.

On the bottom, two progress bars display your effort. The upper bar shows the ratio of totally attempted exercises. The lower bar compares the right with the wrong answers. Do you notice that this is a percentage task too? Mistyped inputs (letters, spaces, and so on) have no influence here.

At any time you can leave this window with the Cancel button. You will be carried back to the welcome window. There you can select another type of task or exit &kpercentage;.

If you press the Apply button you are told whether your input was right or wrong...
