It's just operator precedence:

-1.25992104989487

I've had two attempts at installing the VMWare Player v2.5.2 on a
Windows XP Pro PC. Both times the Player will not start correctly - it
crashes Windows almost immediately the player has started. So I'm not
even getting as far as starting Sage.
So I'm tempted to try earlier versions of the VMWare

Looking at the symbol table, I found one that serves my particular
purpose well: \top. $M^\top$ renders as I'd like for a transpose and
avoids using an unsupported font in jsMath.

OK, I have it working in Sage. How do I start it in an html page?

Thanks for your patience. I am using xwindows on the CentOS server.
When I load the twist.py file using gedit, it looks like an html
file. When I get into Sage I have to type each line by hand? Is
there a easier way? When I am finished the notebook is started. Then
what do I do?

Ciao everyone !
I'm trying to make some computation with matrices (with some variables
x,y,z). For that, I'm following the document :
http://www.sagenb.org/home/pub/217/
When I type (in a notebook) the following, it works :
A = matrix([[7, 0, 0], [0, -2, 4], [0, 6,

Hello,
Looking at the code for load in enlightening. Here's the bit that is
relevant for you:
## Load file by absolute filename
X = loads(open(filename).read(), compress=compress)
try:
X._default_filename = os.path.abspath(filename)

Hi!
When one does
sage: load('path/to/filename')
then eventually some unpickle function (or __setstate__ method) is
called.
Is it possible to determine the value 'path/to/filename' (or 'path/
to/') inside the unpickle function?
In other words: Does the 'load' function temporarily store the va
