Has to warn
House education is a task with three unknown from three, mathematics would not undertake it.
A task with three unknown!
Lets try to solve it as far as it is possible.
Lets touch all three unknown sizes: chapter of the book is devoted to parents, the second to children, and the third, respectively, to the relations between parents and children.
Has to warn that the book will seem to much too difficult, too philosophical.
However it leaves at the end of the century; all readers, at all parents have a secondary education.
