👉 In mathematics, a commutative relation is one in which the two elements being compared must be interchangeable. This means that both elements can be considered as if they were placed next to each other without any change in their position or nature. For example, consider two sets of numbers: A = {1, 2, 3} and B = {a, b}. In this case, the relation "x is greater than y" would mean that x > y for all values of x
