I saw an old Sage LiveCD on sagemath.org. I don't understand how this
is possible since Sage unpacked is 1.5 Gb. A CD can hold around 650Mb

Sage does calculus and geometry calculations so I don't understand why
the term "Computer Algebra System" is so prevalent.
What is the definition of "algebra"? Perhaps "algebra" means something
like "the manipulation of a finite number of objects" ?

Since you nor I did see that, should we ask if there is a way to unify

reason
