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.^{[2]} 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

Figure 1: Set A contains set B. 
Example 2
The set of
real numbers
contains the set of
