They will resist doing assignments that they find tedious. They are far more interested in understanding the theory behind a problem than they are in actually doing the problem. They learn best by theory rather than by example. They need to understand the theory before they can do anything. Let's use division as an example.
Some children learn how to divide numbers best by doing it over and over again.
They learn by example and repetition. Once they have done a lot of different division problems, they understand how it works and are comfortable with dividing numbers. ENPs learn division best by understanding the concepting of dividing a whole number into smaller parts. Once they understand the theory, they can apply this to their division problems and they are comfortable with dividing numbers. ENPs are goal-oriented, and do well when given the goal and left alone to achieve it in their own way.
