I can't think of an argument that makes sense to me to "not show". Showing the work captures the thought process which is really the only thing that matters from an educational point of view (in my opinion). Mostly because that's where one can step in and follow up after the exams and see which students have problems and find the root causes of the problems. Of course most grading is done in a "grade and throw away" manner. Consequently, easier grading has a very high priority. I really whish more educators would see exams as chances to evaluate how well they taught the material and to find areas they could improve.
