A principios del mes de marzo del presente año, en un mercado de los llamados " Mercado de pulgas" me topé ( ya ahora con estas rarezas) y me hizo recordar mis años de preparatoria cuando me enseñaron a usar las reglas de cálculo en mis estudios de la asignatura de Física, es por eso que quiero recabar más información sobre este tema de regla de cálculo dial, agradezco la presente.
