Contain (Set)

Pronunciation: /kənˈteɪn/ Explain

A set contains another set if all the members of the contained set are also members of the containing set.[1] If set A contains set B we can also say the set B is a subset of set A, and write B ⊂ A.

Example 1

Diagram showing set A as a large circle and set B as a small circle all the way inside of the circle for A.
Figure 1: Set A contains set B.

Example 2

The set of real numbers contains the set of integers because every integer is also a real number.
