Web20 Nov 2024 · Let us consider A and B to be two non-empty sets and the Cartesian Product is given by AxB set of all ordered pairs (a, b) where a ∈ A and b ∈ B. AxB = { (a,b) a ∈ A and b ∈ B}. Cartesian Product is also known as Cross Product. Thus from the example, we can say that AxB and BxA don’t have the same ordered pairs. Therefore, AxB ≠ BxA.
