This is the amazing thing about Sage and an attribute of good software: you don't need to understand every detail in order to use it productively. And it motivates you to learn more and explore unknown fields such as mathematics. :)
I just spoke to a Geography professor who said that it would be great to have one software that everyone at the department could use for teaching, rather than confusing students with totally different syntaxes such as those in Matlab, R, MMA, etc. I would add that it would be great if such a program was free so that students could actually apply what they learned after leaving university, without having to buy 10 different software licenses. Why not keep working on such a software? Stan On Mar 26, 12:18 am, Maurizio <maurizio.gran...@gmail.com> wrote: > I don't get it... > > how should this make SAGE easier?
