For the following conditions on a 7485 magnitude comparator, what will be the state of each of the three outputs?
A0 = 0B0 = 1IA < B = 0
A1 = 1B1 = 0IA = B = 1
A2 = 1B2 = 0IA > B = 0
A3 = 0B3 = 0 
A = B = 0, A < B = 0, A > B = 1
A = B = 0, A < B = 1, A > B = 0
A = B = 1, A < B = 0, A > B = 0
A = B = 0, A < B = 0, A > B = 0
