mathematician. I'd like to see the steps Sage uses
to convert the sum I give it (or what not) to the form it chooses.

Hi. When using Sage notebook in typesetting mode, a leading minus
sign doesn't seem to appear.
sage: expand(h_m)
-m^2/(2*n - 1) + m + m/(2*n - 1)
# This is correct. Now, let's turn on typesetting:
sage: expand(h_m)
# Doesn't show the leading minus sign. Here is what the text button
shows:

If I have a rational expression in x, say (2*x^3 - 3x + 4)/(x - 9),
what are the different forms Sage can display it in? I'd like to be
able to:
* Simplify it as much as possible (eg take out common factors,
stipulating that there's no division by zero)
* Factor it as much as possible
But also,
Hi. Checking out sage, and it's amazing. I'm a bit overwhelmed by its
size, though... I intend to use it to handle some of the messy
algebraic manipulations while I work on combinatorics. Can anyone
help with these questions:
1) When I enter a sum in sage:
> h = sum(h_m, m, 1, 2*n)/2*n # h_
