Perhaps with 'iquorem(63,23)[1]' or [2]

Using [1] (or [2]) is ok in CAS, however, and in Home it would perform an implicit multiplication...

Ans(1) should get you 2 and Ans(2) should get you 17 as one way (in CAS)

I totally forgot about that as I ususally always work in CAS. So here a solution is:

L1:=iquorem(63,23);

L1(1), recalls the first element of the result, that is 2

Right...

Maybe it is useful a more general way, that would be valid both in CAS and Home, to extract elements from matrices and vectors [].

i.e. in Home M1(2,3) is ok but [[1,2,3],[4,5,6],[7,8,9]] [2,3] tries to multiply, instead of extracting elements (in CAS that's ok).
