+
+<p>Die Operatorpriorität bestimmt, in welcher Reihenfolge Operatoren ausgeführt werden. Operatoren, die in der Rangfolge zuerst kommen, werden auch zuerst ausgeführt.</p>

+<h2 id="Assoziativität">Assoziativität</h2>
+
+<p>Assoziativität, bestimmt in welcher Reihenfolge Operatoren der selben Rangfolge ausgeführt werden. Betrachten wir als Beispiel den folgenden Ausdruck:</p>
+
+<pre>a OP b OP c
+</pre>
+
+<p>Linksassoziativ (links nach rechts) bedeutet, dass der Code als <code>(a OP b) OP c</code> ausgeführt wird, während rechtssassoziativ (rechts nach links) heißt, dass der Code wie <code>a OP (b OP c)</code> ausgeführt wird. Zuordnungsoperatoren sind rechtssassoziativ, also kann man schreiben:</p>
+
+<pre>a = b = 5;
+</pre>
+
+<p>mit dem erwarteten Resultat, dass sowohl <code>a</code> als auch <code>b</code> den Wert 5 haben. Das liegt daran, dass Zuordnungsopertoren den Wert zurükgeben, den sie zuerst zugeordnet haben: Zuerst wird <code>b</code> auf 5 gesetzt; daraufhin wird <code>a</code> auf 5, also den Rückgabewert von <code>b = 5</code>, gesetzt.</p>
+
+<h2 id="Tabelle">Tabelle</h2>
+
+<p>Die nachfolgende Tabelle geordnet von der höchsten (20) bis zur kleinsten (1) Priorität.</p>
