Best ResponseYou've already chosen the best response.0It would make sense that the "bar" means "the set that the number belongs to" For example, in the picture all number that are evenly divisible by 3 (i.e. have 0 as a remainder) belong to "set \(c_0\)" thus it makes sense to say the set containing 4 equals the set containing 7 because both numbers belong to set \(c_1\) , and \(\bar{4} = \bar{7}\) is true.
