If A = {0, 1, 2, 3} and B = {…−3, −2, −1}, what is A ∩ B? {…−3, −2, −1, 0, 1, 2, 3, …} {…−3, −2, −1} {0, 1, 2, 3} { } Would it be A?

    Finally. Getting tired of inequalities :D The intersection of two sets A and B, denoted A ∩ B is the set of all the elements they have in common. DO they have any elements in common? ^.^

    Yes, PRECISELY :) They have no elements in common :) Think of it this way A ∪ B is the set of all elements in A OR B A ∩ B is the set of all elements in A AND B
