Microsoft Word, for example, cannot teach us how to write but it helps us during the writing process. In the same way, the SageMath program cannot teach us mathematics but it can help us to do mathematics. Mathematical software of this kind liberates us from routine calculations. However, routine calculations cannot liberate us from understanding, as someone might think. This kind of software is today what logarithmic tables and calculators were in the past. And more than this – besides more powerful numerical calculations, this kind of software performs symbolic calculations and helps us to visualize problems in order to better understand what happens and to gain qualitative answers.
