Abstract

CHILD TABLE TO ADD AND REST, indistinctly, which consists of a reglilla that has been marked on one of its edges a number of strokes correlatively numbered (the strokes, not the spaces) from left to right from one. To the left of the one there is a zero, without any trace. Another similar ruler has a piece of cardboard stuck on one of the edges, and on it, lines arranged as in the previous rule. By sliding the second rule over the first one, it partially covers the strokes of it and allows us to carry out the operations. (Machine-translation by Google Translate, not legally binding)
