<PRE><B>Question 433982</B>
How do I find the intersection: Given U {10,11,12,13,14,15,16,18,19,20}
A{12,14,16,18,20}
B{11,13,14,15,18,19,20} 
Find A intersect B
-------
The intersection of Park Ave and 1st St. is the part
of the road that is on Park and also on 1st.
----
Similarly:
A intersect B = {14,18,20} because each of those is in both A and B.
