+    \item Wanting to show:
+        $A \cap (B \cup C) = (A \cap B) \cup (A \cap C)$
+
+        In order to prove this equivalence, we have to prove the implication both ways. We use two lemmas for this.
+
+        \begin{lemma}[test]
+            $A \cap (B \cup C) \implies (A \cap B) \cup (A \cap C)$
+
+            Let $x \in A \cap (B \cup C)$.
