It is better to deduce from the basic definition than throw out a large number of concepts at one time. The students can not digest it, but also hinder the understanding of the basic concepts. Of course, the best way is to start from the basics and to add nuance as the student progresses. In the principles of economics, it is from the ten principles of economics
