The main properties and objects that emerge with this way of operating quantities are exposed. Finally, the antiderivative and the indefinite integral are defined in order to calculate the primitive of in the Proportional context.Acceso AbiertoProportional arithmeticcalculusteaching differential and integral calculushttp://dx.doi.org/10.1080/0020739X.2020.1763489
