Situation mathématique

English : Mathematical situation
 "A mathematical situation is a set of specific conditions in which a determined set of mathematical connaissances (stated or belonging to the milieu) permit a subject to realize a declared project by the exercise of appropriate mathematical connaissances, known or original. Note that this description applies not only to students but also to mathematicians" (Brousseau et al. 2014 pp.202-203)
