  Information and Community Technologies (ICT) are very present in our society
nowadays and particularly in the educative field. In just two decades, we have
passed from a learning based, in many cases, on the master lessons to one such
that methodologies like the flipped classroom or the gamification are stronger
than ever. Along this work, we have done a study to teachers and students with
the main objective to compare the knowledge on digital tools, their use and
their acceptation. We use WxMaxima and Geogebra in order to solve an exercise
of \textit{Evaluaci\'on de Bachillerato para el Acceso a la Universidad} (EBAU)
related with Geometry, comparing their ins and outs with the manual solution.
Finally, we expose some conclusions and some possible research lines about
digital tools, as well as a proposition of an introductory course on WxMaxima
and Geogebra in order to teach the teachers.
