Some computations. An important thing: everything is mathematically typed in Axiom.


(1) -> 1+1

   (1)  2
                                                        Type: PositiveInteger
(2) -> integrate(1/x^(1/3),x)

         3+-+2
        3\|x
   (2)  ------
           2
                                          Type: Union(Expression Integer,...)

Axiom is running under Windows.

Some matrix computations under TeXmacs ?.
