摘要

Assembly for and inequau00e7u00e3o equation of first degree, ratio and proportion, relationship directly and indirectly proportional refers to a set of equation and inequau00e7u00e3o of first degree, reason and the proportion relation directly and indirectly proportional, situated in the technology sector of Equipment for teaching and research in the study of mathematical functions.It appears that are non-existent equipment intended to promote the understanding and study of mathematical functions, more specifically, the study reason and proportion relation directly and indirectly proportional, hindering their understanding as they are eminently ABS issues Treatment.It is characterized by a balance (1) composed of a central database (2) provided with a positioner or caliper (3) and is provided with a rectilinear element in the pendulum (4), which is provided with indicator of balance (5), and in whose arms (4a) and (4b) are positioned magnu00e9tic axes. The magnetic or not (6), in which it may be placed masses widgets (7),Movable plates (8) with balls (9); and, the magnetic or non-magnetic shaft (6), which are capable of positioning over the arms (4a) and (4b).
