  • 摘要:This work of research describes a procedure of building a holistic ranking of diffi culties associated to the additive strategies of mental calculus. This procedure is based upon calculus basic activities which determine the strategy, and, through it, we establish a holistic classifi cation of the difficulties of calculus associated to those strategies. This paper ends up by stating the conclusions and pointing out a couple of open problems.
