Notice that there are, in fact, \(6\) elements in \(A \times B\) and in \(B \times A\text{,}\) so we may say with confidence that we listed all of the elements in those Cartesian products. B The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. All counting modes are connected via the relation "total elements = unique elements + repeated elements". endobj \newcommand{\Tg}{\mathtt{g}} }\), We can define the Cartesian product of three (or more) sets similarly.
