Hi,

how can I print this

 __n__
 |   |
 |   | i
 |   |
  i=1

(Similar to \sum, but not adding but multipling. While \sum is a \Sigma,
this product sign
is a \Pi.)

Is there a simple way typesetting this

A = B  }
        } => A=C
B = C  }

i.e. if I have two equations and a third can be concluded from the two.
[this ,}' cascade was ment as one big brace]

I might miss something, but how is \setupformulas supposed to work?:
\stelleformelnein[position=links,links=LText,rechts=RText]
appears as
         [formula]           LTextRText
and \stelleformelnein[position=links]
         [formula]           (1)

BTW: Is there a simple methode to have math formulas left justify?
And how can I have something like this:
\item $$xxx$$ 

without getting this result:

12.
                         xxx
