Calculating machine, which is essentially characterized by comprising a base with an inclined upper surface, where a series of rotating discs linked in the body of the surface are arranged in line and which appear outside exclusively by a zone of circular crown, with a lower point from top, where the crown is cut, and comprising a top window through which appears an outer part of each disk, which has recorded all around the figures from zero to nine, comprising this disk in its visible crown area ten entrants at an equal distance from each other to anchor the end of a pointer, operatively arranged to effect the manual rotation of each disk and so that with each complete turn of a disk, perform the following one tenth of a turn, and presenting the corresponding surface to each disc entrant recorded the figures indicating the zero to the nine in both directions corresponding to the disc turns in sen counter-clockwise for the sums, and in the opposite direction for the subtractions.
