ring R=integer,(x,y,z),dp;

* You are using coefficient rings which are not fields.
*

**Please note that only limited functionality is available**

**for these coefficients.**

**The following commands are meant to work:****- basic polynomial arithmetic**

**- std****- syz**

**- lift****- reduce**

poly f=27xy; ideal I=-3xy+z; I=std(I); I;

I[1]=-3xy+z

reduce(f,I);

-9z

Hier sollte 9z rauskommen.
