We used maxima extensively in high school. I remember that I forgot to bring my laptop when we had our first maxima lesson. My teachers understandably scolded me for not bringing my laptop to school, but to their surprise I found an online version of maxima. [1] While it was good enough for this period, in contrast to this implementation it was truly awful.

I just think it's kinda sad that a lot of people never heard of maxima, as it is a pretty decent tool once you learn how to use it.

That sounds stupid. What if someone doesn't have a laptop? Even if do, cannot see why one's obligated to bring it along.

It surely has the advantage of interactivity. The version you linked seems to restart the session in every query. On the other hand, seems more stable. Both `invert(matrix([2,3,1], [a,0,0], [1,4,8]));` and `draw3d(explicit(x^2+y^2,x,-1,1,y,-1,1));` that run fine in UFV's DMa version fail to run in the submitted one.

Where I live, the school issues laptops to students, so not bringing the laptop is today's not bringing your textbook. (As a point of fact, my daughter is in 10th grade and has had exactly one physical textbook so far; the rest have been digital)
