Ahh...I apologize for creating extra noise then. :-(

All that you need to do is to copy the texmf-modules directory from a standard context distribution to the lmtx tree.

OK. Will try to do it.

If you are intending on preparing math exams, I may suggest that native MetaPost IS better adapted for many reasons AND easier to use in ConTeXt.

I believe it is, but it seems that learning curve is steeper, while GeoGebra is quite easy to easy...However, I downloaded MetaPost manual and will test how it goes.

Because your (or someone's) mail application replaced -- with emdashes.

Thank you very much - it is very useful for learning purposes.

That's great and desirable!

Wow!! This is wonderful example and learning resource. Thank you, all, for your replies. Such a friendly and helping list/community! Sincerely Gour -- A person is considered still further advanced when he regards honest well-wishers, affectionate benefactors, the neutral, mediators, the envious, friends and enemies, the pious and the sinners all with an equal mind. -- From anger, complete delusion arises, and from delusion bewilderment of memory.
