You gave a perfect answer, much better than I expected. But I mean, a long time ago, 1+1 meant, "Look, Harry, what that eccentric Pythagoras is talking about again." Some research can be difficult, like how to kill this mammoth, or how to kill any mammoth, or how to make a livestock farm so there is always fresh meat. But mathematical research is the most difficult, because only the most omnipotent knowledge is considered mathematics. That's why OP's point [1] is valid but maybe the definition of "mathematician" word is missing for making the question interesting.
