Well for one it's prompting you to make a meaningful linguistic exercise of the matter, which is at once a creative task and secondly it enforces a more dynamic approach to whatever problem is presented. I wonder if you could get a professor to do anything more than plug and chug, and that's a skill we've long ago delegated to glass. Not only do I want to explain these things in my mother tongue, I expect to know why some variable is in some such place, and how a cube of some other variable is related to the problem at hand. Calculation is banal.
