WebMar 24, 2024 · Definition: Cartesian Product The Cartesian product of A and B is the set A × B = {(a, b) ∣ a ∈ A ∧ b ∈ B} Thus, A × B (read as “ A cross B ”) contains all the ordered pairs in which the first elements are selected from A, and the second elements are selected from B. Example 4.4.1 Let A = {John, Jim, Dave} and B = {Mary, Lucy}. WebOffice: BH 184A Email: [email protected].
