I have downloaded Galois theory package from http://library.wolfram.com/infocenter/Articles/2872/ and I currently have Mathematica v 12.0.
When I loaded the module (I needed to delete the blue stuff in the beginning for it to work properly), I entered these commands into notepad:
Define[a^3, 2] Define[b^2, -a^2-ab] Factor[x^3-2, a, b]
As per the notebook file, this should output
(-a + X) (-b + X) (a + b + X)
But this is outputting
(Also when I load the package, it's showing some errors like
Tag Norm in Norm[Poly_, a Symbol] is protected])
I am a complete noob in mathematica so don't bash me if this turns out to be a trivial issue.
