>>12499408equality between sets is when all elements of set A are included in set B, and vice-versa for all of set B's elements being included in set A
let set A be {8; empty set}, let set B be {8; empty set}
for these sets, every member of set A is included in set B
for these sets, every member of set B is included in set A
ergo, set A is equivalent to set B
8=8
