reading Ralf'ss explanations again should make that clear. Actually,
this really is the strength of FriCAS. The trick is only for convenient
typing in.

I appreciate your help Professor Grabmeier. I must admit I'm astonished to
learn that we need tricks to do elementary algebra in a computer algebra system.

To Ralf's very useful remarks to answer your question let me add the
following trick, which seems to be very userful for beginners, too: The
trick is to define (interpreter) variables a, b and c which point to
objects in the desired distributed domain, which are a, b, c. This
forces the interpreter not to choose Polynomal Integer , but direktly
allows to do the desired operation in dmp.
(7) -> dmp := DMP([a,b,c], Integer)
(7) DistributedMultivariatePolynomial([a,b,c],Integer)
Type: Type
(8) -> a : dmp := a
(8) a
Type:
DistributedMultivariatePolynomial([a,b,c],Integer)
(9) -> b : dmp := b
(9) b
Type:
DistributedMultivariatePolynomial([a,b,c],Integer)
(10) -> c : dmp := c
(10) c
Type:
DistributedMultivariatePolynomial([a,b,c],Integer)
(11) -> (a+b)*c
(11) a c + b c
Type:
DistributedMultivariatePolynomial([a,b,c],Integer)
