Question

the intersection of the set of positive integers and the set of negative integers

find the intersection.

Answer 1

the intersection of two sets is the set of all things that are in BOTH sets (ie what they both have in common)

Answer 2

for instance

if A = {1, 2, 3, 4} and B = {5, 7, 3, 9, 4}

then

A intersect B = {3, 4}

because 3 and 4 are in BOTH sets
