In French, we name that "les mathématiques"... ISTR that there are serious
etymological reasons. The US's "math" sounds like carelessness (and the
french "désinvolture" would be a better designation...).

In Great Britain "mathematics" is abbreviated "maths". In the US,
"mathematics" is abbreviated "math".

In the headings of the quick start it says things like "Symbolic *Maths*"
and "Numerical *Maths*"
It is MATH not MATHS.

Hmmm...
sage: assumptions()
[]
sage: (z-4*conjugate(z)).simplify()
-3*z
sage: assume(z,"complex")
sage: (z-4*conjugate(z)).simplify()
z - 4*conjugate(z)
Explicitly telling "var(z,"complex") has the same effect... This seems
directly inherited from Maxima :
(%i29) ratsimp(z-4*conjugate(z));
(%o
I think you've asked the wrong list. This is for SageMath: www.sagemath.org.

Hello everyone,
First all, I am completely new to SAGA as well as GIS. However, I thinks
this perhaps just a configuration error on my side on my linux host.
I am using arch linux with gcc 7.2.0
I have just cloned the recent version from git.
[michael@moo:saga-gis-code|master]$ git remote sh
This is probably related to the following:
sage: var('z')
z
sage: (z - 4*z.conjugate()).simplify()
-3*z
which is a bug, given that the documentation of var says:
By default, var returns a complex variable

Is the following a known bug?
sage: var('z')
z
sage: z0all = solve(z - 4*z.conjugate() == 1 + 3*I, z); z0all
[z == (-I - 1/3)]
sage: z0 = z0all[0].rhs(); z0
-I - 1/3
sage: (z0 - 4*z0.conjugate()) - (1 + 3*I)
-8*I
Clearly, the result of solve is not a solution of the given equation.
