Question
Let A = {1, 2, 4, 5, 6}, B = {2, 3, 4}. Then A \ B is
Solution
The operation "\" in set theory is the difference of two sets. It is denoted as A \ B and it means the set that contains all the elements of A that are not in B.
Given A = {1, 2, 4, 5, 6} and B = {2, 3, 4}, we can find A \ B by removing all elements in set B from set A.
So, A \ B = {1, 2, 4, 5, 6} \ {2, 3, 4} = {1, 5, 6}.
Therefore, A \ B = {1, 5, 6}.
