Find A Intersected B

Let n = intersection of set A and B.

Set A = { 1, 3, 5, 8 }

Set B = { 3, 5, 7 }

Let me see.

A n B =  { 1, 3, 5, 8 } n  { 3, 5, 7 }

A n B = { 3, 5 }

You say?

Thank you. I find sets to be fascinating.  Michael Sullivan introduces the basic ideas of sets in his Review Section 1. In fact it is the very first topic that Sullivan introduces in his College Algebra Edition 9 textbook.
