[kde-edu]: Simple arithmetic apps

[John Lamb]

I wrote a Qt version of what I was looking for and put it on
http://www.uyea.btinternet.co.uk/sums.tar.gz
It's not very sophisticated, but it will compile and run. If anyone 
wants to do anything with it, just take the code and apply the GNU GPL...

That would be nice too. My idea was something that would help a 6-8 year 
old memorise addition and subtraction rules, but multplication tables 
are a good idea too. I guess the ideal thing would be to collect some of 
these together.

Actually, I prefer C++. But Python is great for testing ideas. I wrote 
the Python script in 15 minutes but it took 2.5 hours to write the same 
thing in C++/Qt (see above).

I used XEmacs: I've yet to try KDevelop, though I bet it would write 
better makefiles. designer helps a lot. Although I haven't used Qt much 
before and not recently, I found it nearly as nice as Java and much, 
much better than M$VC++ to work with.

Nice idea. It could work also for a younger age group, perhaps with just 
+ and -.
