LIMA, Amanda Cardoso Benicio de; SOARES, Kawoana da Costa  y  PEREIRA, Ana Carolina Costa. Dialogue on the arithmetic knowledge contained in the manipulation of two slide rules by William Oughtred. Ed. Mat. Deb. [online]. 2023, vol.7, n.13, e1f.  Epub 01-Ene-2023. ISSN 2526-6136.  https://doi.org/10.46551/emd.v7n13a07.

This article presents the multiplicative process involving William Oughtred's (1574-1660) two rulers for calculations, published in 1639 in The Declaration of The Two Rulers for Calculations, an addition to the treatise The Circles of Proportion and the Horizontall Instrvment. For this, we used a methodological approach of documentary research, searching through primary and secondary sources. Thus, we can see that the multiplication operation performed by the apparatus can develop in teachers in initial and continuing education concepts related to proportionality, order and class of the decimal system and properties of logarithms, bringing a practical meaning to a historically sedimented school mathematics.
