This is popular booklet about the names of all digits and of more important numbers in different languages, about their graphical images, and about all possible ideas hidden behind them. The questions are sufficiently complicated and lost in the darkness of centuries, as is said, they maybe are partially explained somewhere, but the author has come to them alone. These are things interesting for everybody, they, in principle, are not difficult, but as far as they require mathematical knowledge and profound etymological researches they are known practically to nobody (well, say, some 2-3 % of people guess about something, but surely not about all things). So that this is also serious scientific paper, only popularly written.   Keywords: digits, numbers, etymology ancient languages, ideas, original work.
