An operation performed on members of that set will result in a member of the same set.
The set has a finite number of members, as opposed to being infinitely large.
An expression belonging to a closed set cannot be used to create an expression that is not of that set.
Members of a closed set cannot be added, subtracted, multiplied, or divided.

The correct definition for a set to be "closed" is:
An operation performed on members of that set will result in a member of the same set.
This means that if you take any two elements from the set and perform the operation (like addition, multiplication, etc.), the result will also be an element of the same set.
