Yes, but to calculate with fractions you need the ability to find the
smallest possible denominator of 2 terms. Normally you can do this by
finding the primefactors of the different denominators.

Yes, of course we would need a complete math tool, but we don't have it yet.
So I think a good way is to extend a given program step by step. I think
programs are allowed to evolve. For example in the beginnings Netscape was
just a web browser. Today it is a messaging suite with web, email, news,
html editor and so on.

It won't happen. It is easy to influence the generation of the number which
should be factorized. There could be different levels.

That's what I'm thinking about for the future. It won't happen till KDE 3.3,
because during this release cycle I was working (and I am still working) on
my diploma thesis and had no time to do much for KDE at all. I also like to
integrate parts of kmathprof...

I will have a look at it.

Yes. You want to change the number of ratios and the max. denominator. In
this case 2 new tasks would be generated. And 2 tasks would be count as not
correctly solved.

Yes. I will do this before KDE 3.3 string freeze.
