Why is the universal relation (A\times A) symmetric on any set (A)?

Answer and explanation

Correct answer: Because every ((a,b)) comes with ((b,a))

Step 1: (A\times A) contains all possible ordered pairs from (A). Step 2: If ((a,b)) is in it, then ((b,a)) is also definitely in it. Step 3: The universal relation is one of the simplest examples of a symmetric relation.
