摘要

The number sets \({\mathbb N} \subseteq {\mathbb N}_0 \subseteq {\mathbb {Z}} \subseteq {\mathbb Q} \subseteq {\mathbb R}\) are known from school. However, this chain of nested number sets does not stop at \({\mathbb R}\) . The complex numbers form the number set \({\mathbb C}\) , where \({\mathbb R} \subseteq {\mathbb C}\) applies.
