When are two sets called equal?
Answer and explanation
Correct answer: When all their elements are the same
Two sets are equal if and only if they contain exactly the same elements. The names used for the sets do not matter, and the order in which elements are written is irrelevant because sets are unordered. Having only one common element is insufficient; every element of each set must belong to the other set.
