Das kartesische Produkt enthält alle geordneten Paare der Elemente aus $AA$ und $BB$:

$A\times B=\{(\mathrm{2,6}),(\mathrm{2,7}),((\mathrm{2,4}),6),((\mathrm{2,4}),7)\}A\; \backslash times\; B=\; \backslash \{(2\{,\}6),(2\{,\}7),\backslash big((2\{,\}4),6\backslash big),\backslash big((2\{,\}4),7\; \backslash big)\backslash \}$

$A\times C=\{(\mathrm{2,5}),(2,(\mathrm{6,7})),((\mathrm{2,4}),5),((\mathrm{2,4}),(\mathrm{6,7}))\}A\; \backslash times\; C\; =\; \backslash \{\; (2\{,\}5),\backslash big(2,(6\{,\}7)\backslash big),\backslash big((2\{,\}4),5\backslash big),\backslash big((2\{,\}4),(6\{,\}7)\backslash big)\backslash \}$
