Equality of Sets

Pronunciation: /ɪˈkwɒl.ɪ.ti ʌv sɛtz/ Explain

Two sets are equal to each other if they contain exactly the same members[2]. Stated mathematically: A = B iff AB and BA. This means that if set A contains everything in set B and set B contains everything in set A, then the two sets have exactly the same contents and are equal.
