The mathematics professor must perceive its unfinished state of (FREIRRE, 1996), that is, that he must recognize the necessity to be always in search of new knowing. The true professor of mathematics is that one that beyond knowing the content very, it must contain in its essence the capacity to know to teach mathematics, to know to work in group, of being creative, and never to be egoistic.

He has that to assume its professional role not neglecting its activity. The professor of mathematics of the gift must transmit information, instruct, mediate, teach, learn, evaluate, educate and educate for the research. To educate for the research is to make with that the pupil learns to work for the method of research with the purpose to exercise, to construct always improvements and always to surpass barriers and difficulties.
