"Light" versions of our commercial programs give you an opportunity to try all functions of our programs gratis and to make your own conclusion whether this program suits you. All functions of commercial programs are shared by their Light versions. The differences are as follows:
- The scope of topics: Light versions include all the developed themes, but coverage is rather fragmentary. Included are a couple of randomly chosen sections from a few chapters. Light versions are not fit for a systematic study of math.
- The database volume: the number of problems attached to each topic is rather small.
- The advertising messages appear at every loading of each Light version. In commercial programs, the advert is absent.
An important remark: Light versions are not the demonstration versions. These are fully functional programs operating on a database comprising about thousand math problems. Such data amount is comparable with databases of many existing commercial programs.
