+$R$ ein Ring, z.~B.~$\mathbb{Z}$, $\mathbb{Q}$, $\mathbb{R}$

+\begin{definition}
+Polynome in $X$ mit Koeffizienten in $R$:
+\[
+R[X]
+=
+\{
+a(X)\;|\;
+a(X) = a_nX^n+a_{n-1}X^{n-1} + \dots a_2X^2+a_1X + a_0, a_k\in R
+\}
+\]
+\end{definition}

+\begin{itemize}
+\item {\em Grad} des Polynoms: $\deg a(X) = \deg a = n$
+\item $\deg 0 = -\infty$
+\item {\em normiertes Polynom}: $a_n=1$
