Грядёт замена #wxMaxima ?
Оказывается в #KDE предлагается универсальный GUI для систем математики: #Cantor — https://apps.kde.org/cantor/

Заявленный перечень environments включает: #KAlgebra, #Maxima, #Sage, #Scilab, #Qalculate Т.е. полноценные, давно и хорошо известные системы computer algebra system (CAS) or symbolic algebra system (SAS).

Хотя это скорее дополнительный вариант, тем кто на #linux привык использовать #wxMaxima — https://wxmaxima-developers.github.io/wxmaxima Решает в алгебраическом виде уравнения и системы, численные вычисления, построение графиков. По возможностям близка к Maple и Mathematica.

Из забавного позволяет видеть графики в динамичном виде:

И в целом всё то, что потом перешло в питоновский Jupyter как notebooks:

This is a subtle math education question.
Consider this sequence of algebra steps:
a+b=c given
a=d given
d+b=c substitute

This is substitution. And feels natural to me. Replace a with d. But, I have many students who write:

a+b=c given
a=d given
b+d=c substitute

Still correct but I don’t understand why they swapped the order. What are they thinking? If it was just one or two students I’d call it “the noise of young minds” but it’s six of them. Why do they write it like this? #mathematic

How does weight relate to speed and gravity? Can a body become infinitely fast just because gravity accelerates it? What exactly happens in the process? Or linear algebra, which I'm learning right now. What else is a vector transformation if not a transformation of space itself? The mathematics we are supposed to learn in school is really just an oil slick on a very deep body of water where many fascinating ideas live.

A friend asked me:

"What is math if not calculating?"

I thought about it.

Mathematics is an abstract view of reality. It is a language in which we describe patterns and relationships, quite often only by letters that stand for forces, movements, ratios and so on. Of course, in the final step, numbers are used for these letters to calculate something, but the mathematics itself is actually all that happens before that.
