I found a message on sage-devel list (http://www.mail-archive.com/sage-
de...@googlegroups.com/msg10351.html) about an inequality solver.
However, each time x is a divisor of something (therefore it cannot be
zero), the isolver function fails, as it tries to find the zeros of x
as a solving strate

Hello all,
I am trying to install sagemath-3.0.5dfsg (i386) from repository. I am
running Kubuntu 9.04.
I am getting "dependency resolution failed" and it directs me to
remove "libgd2-noxpm" module. KPackageKit is not progressing in
installation process due to this issue. Is there any workaround
Ah, that explains it! I tried
b = FormalSum([(2,'x')],parent=GF(7))
when I should have tried
b = FormalSum([(2,'x')],parent=FormalSums(GF(7)))
The latter gives me
sage: 5*b
3*x
sage: 5*b == 12*b
True
and this is what I wanted.
Thanks a lot,
Christian

Your mistake is to force the parent to be GF(7). The parent is not
the coefficient ring. Try
sage: FormalSum?

Is there a way to find the domain of x given a simple inequality like 5*x +

was wondering if could use Sarge in a high school math class, so this is of
big relevance.
