Question

intersection of sets?

Answer 1

For set A and set B, that is the set of points in both set A and B.

Answer 2

okay, the intersection of two sets A and B is element that are common between A and B
lets say that A:{1,5,3,7,8,10,22}
set B:{10,7,11,14,3,2}
observe that {3,10,7} are common between the two sets
therefore the A intersection with B is {3,10.7}
