I just fixed it in the patch on #7496:
sage: var('2x')

If you are writing code to include in .py files, then
After four and a half hours of compillation my sage looks good,
even though I received one warning message
"dvipng command 'dvipng' cannot be run (needed for math display),
check the pngmath_dvipng setting"
The R-package installation option works.
Starting sage in terminal do not produce

I'm wondering how difficult it would be to bring this package into Sage?
I realize there is no all-things-for-all-people math package, but I suspect the
author of the project was not aware of

Either one is fine.

the difference is, that var(..) itself already injects a variable with that
name into the global namespace, where the other one is an assignment.
i.e.
z = var('y')
gives you a variable y (named "y") and a variable z with the name "y"
sage: z = var('y')
sage: z
y
sage: y
y
you can also create i
In some tutorials, when a variable is declared, it is done like,
var('x')
In some others, it is done like,
x = var('x')
What is the difference between the two, if any?
Also, is it better to ask this kind of basic question in the Asksage
forum or the sage-support mailing list?
Thanks for your

Yes, it does. But I really had never noticed, since usually I start

Hi Dimitrii and Simon,
Finally I was able to compile the package nq (after installing glibc
and gmp static versions).
I installed also alnuth and polycyclic, but the order
gap_reset_workspace() is not enough
in my installation. I will try other solutions. Best, Enrique.
