Re: what calculator do you use?

[Jörg-Volker Peetz <jvpeetz@web.de>]

In this category of computer aided mathematics or computer algebra systems,
there are also the packages sagemath, octave or scilab.
octave and scilab bring there own GUI.
sagemath and also python 3 or R can be used via jupyter notebook which is a kind
of browser based GUI.

But these are all way to heavy programs for doing simple calculations.
For that I also use `bc -l`. It has a line editor: you can write your whole
calculation in one line and scroll back to previous lines to change and repeat them.

Jörg.
