Interval: all the numbers between two given numbers. Example: all the numbers between 1 and 6 is an interval. All The Numbers? Yes. All the Real Numbers that lie between those 2 values. Example: the interval 2 to 4 includes numbers such as: 2.1111. 2.5. 2.75. 2.80001. π. 7/2. 3.7937. And lots more! Including the Numbers at Each End?
Sets are commonly defined in roster notation or set-builder notation. Roster notation provides a listing of each element in the set. For example, the set P of prime numbers between 0 and 10 (excluding 0 and 10) in roster notation is written as: P = { 2, 3, 5, 7 }

A set is a collection of objects (without repetitions). To describe a set, either list all its elements explicitly, or use a descriptive method. Intervals are sets of real numbers. The elements in a set can be any type of object, including sets. We can even have a set containing dissimilar elements.
17 kwi 2022 · The set consisting of all natural numbers that are in A A. and are not in B B. is the set {2, 4, 6}. {2, 4, 6}. These sets are examples of some of the most common set operations, which are given in the following definitions. Definition: intersection. Let A and B be subsets of some universal set U.
