Students will learn how to find the intersection of two or more sets.

\(A = \{a,\,b,\,c,\,e\}\quad\ B = \{b,\,f,\,g\}\quad\ A \cup B = \mathop{?}\)

\(A \cup B = \{a,\,b,\,c,\,e,\,f,\,g\}\)

\(A = \{1,\,3,\,5,\,7,\,9,\ldots\}\quad\ B = \{2,\,4,\,6,\,8,\,10,\ldots\}\quad\ A \cap B = \mathop{?}\)

\(A \cap B = \{1,\,2,\,3,\,4,\,5,\ldots\}\)
