I always have Octave open for calculations and math. For symbolic math
look at python-sympy, axiom, cantor, euler, form, freemat (said to be mostly
matlab compatible), mathomatic, maxima, sagemath, wxmaxima, or just do
"apt-cache search math" and look down the list.

So do I. Several of them, in fact
Somewhat OT, but (maybe) interesting anyway?
For a long time, I've been aware of the program Mathmatica (by Wolfram

their finger tips ;-)

People live happier when their "bash" is actually a zsh:

I'm aware of bc, but it seems cumbersome.
I would like to just type 'sin 1' and get the sine (of 1 radian),
