The welcome window lets you choose the type of exercise by clicking on one of the buttons. The buttons are labeled with the value to be deduced in the exercises.
On the left hand the number of exercises can be selected. One can choose from 1 to 10 tasks.
On the right hand you can change the level of difficulty:
Only percentages with easy to calculate values are given.
Harder percentages are included, even some with values greater than 100%
Any percentage up to 200% may occur. All values are whole numbered however, so be honest, calculate them in your head!
There are some help functions integrated. As usual some tool tips arise when the mouse is over a control element like a button or an edit line. If you click on the button, a little menu pops up with further opportunities:
Invokes the KDE Help system starting at the this application help pages. (this document).
Changes the mouse cursor to a combination arrow and question mark. Clicking on items within this application will open a help window (if one exists for the particular item) explaining the item's function.
Opens the Bug report dialog where you can report a bug or request a “wishlist” feature.
This will display version and author information.
This displays the KDE version and other basic information.
