The set of people who answered this question before I did. There is only one empty set (a consequence of the Axiom of Extensionality). So the above answer is correct, and is equal to every other example.
Sets are collection of distinct objects. In mathematics there are different types of sets like Finite set, Infinite set, Universal set, subset, equal set, equivalent set. Example of Finite set {1,2,3,4}. Infinite set:{1,2,3....}.
equal set mean the set is equal equal est means that the set is equal
Sometimes. For example, a rectangle has one set of four equal angles, and a parallelogram has two sets of two equal angles.
A = { 0 } B = { 0, 1 } Or, in fact, any set would would, as long as A = B. Or A = an empty set.
