WebApr 17, 2024 · Definition: Cartesian product. If A and B are sets, then the Cartesian product, A × B, of A and B is the set of all ordered pairs ( x, y) where x ∈ A and y ∈ B. We use the notation A × B for the Cartesian product of A and B, and using set builder notation, we can write. A × B = {(x, y) x ∈ A and y ∈ B}. Web1. Our goal is to show that A × B = A ′ × B ′ by finding a bijection (one to one and onto function) from A × B to A ′ × B ′. That is, we want a bijection h: A × B → A ′ × B ′. Once we've found this bijection, we'll know (by the definition of cardinality) that these (product) sets have to be the same size.
