[kde-edu]: Simple arithmetic apps

[John Lamb]

Is there anything out there that does tests basic mental arithmetic 
skills (addition, subtraction, multiplication tables) for 6-8 year olds?

To illustrate this, I knocked together a python script (below), but it 
would be nice to have something like this in Qt/KDE. I guess it wouldn't 
take even me long to write something if there's nothing already.
