Cool, a feature request ;-) I mean I can't add features if I don't know what
the user would like.

Well the idea behind KBruch is, that it is a trainer and not a teaching app.
So visualization is more teaching than training I think. But I would add it
after we found a way to combine all MathApps under one app.

Ok. Do you know a good algorithm to convert 0.125 into 1/8?

Some weeks ago I got a mail telling me, that these numbers like 2 1/3 seem
to be very regional used. The man was from Swiss and has never seen this
before. He thought about 2 1/3 being 2 * 1/3 and not 2 + 1/3. So I don't
know if it is really good to do that.

This is allready done a little bit. If the user enters 3/9 as result he gets
a hint that he doesn't reduced the solution.

I'm very sure this is allready avaible in KControl. Look under Personal
Setup/Country&Language/Figures (Persoenliche
Einstellungen/Land&Sprache/Zahlen).
