Answer 2

Step-by-step explanation:

The most basic properties are that a set can have elements, and that two sets are equal (one and the same) if and only if every element of each set is an element of the other; this property is called the extensionality of sets.

The importance of sets is one. They allow us to treat a collection of mathematical objects as a mathematical object on its own right. ... We just specify our objects. So it's not hard to see that, for example, there is no one-to-one correspondence between a collection of five objects, and a collection of four objects.
