Abstract

A circular rotary abacus for arithmetic operations, characterized by being constituted by two concentric circles coupled by their center so that they can rotate independently of each other, each of them presenting, in the vicinity of its periphery, a circular crown with one hundred radial divisions, numbered consecutively from 1 to 100, the coupling between the two circles being a simple device allowing the rotation of said circles to keep them in their relative position, and said turns being measured by the angular displacements between the two zeros of those indicated circles, respectively endorsement and rotor, presenting the set, to facilitate the calculation, a radius visor of transparent material that, coupled to the same center, can rotate together with any one of the circles or independently thereof, said radio being provided of an index in the form of a clamp that can slide or all its length and therefore traverse during the rotation of the radius visor any one of the arcs or concentric circles that has indicated the rotor in its central area.
