Elementary Mathematics

The main reason for translation of this text book system divided into 19 sections is a renewed interest in a text book on mathematics as it was outlined some 30 years ago. That is a rigorous presentation, where all proofs are completed. Until 1988 Mathematics were teached on a fairly high theoretical level in Denmark. This was possible because the students mathematical skills at that time were vastly better than today.

After 1988, the way of teaching mathematics changed, the traditional theoretical level with proofs, derivations and rigorous expanations were dropped, and replaced by teaching how mathematics could be applied in daily life society.

By the reform in 2005, the theoretical aspect almost disappered completely, and elemmentary mathematical skills were discarded in favor of operating mathematical computer programs. The education has turned from theoretical to lexical.
A development in the educational systems towards the ideology of social constructivism, which I sense is more or less shared by most of the Western world.(But not in Asia)

The reason for the renewed interest for a more than 10 years old textbook is that they do simply no longer exist, neither as textbooks or internet pages material,were you get a traditional rigorous theoretical explanation of mathematics in a level, which nowadays is placed at university undergraduate level.
