      When A-B is given, We need to find the number of values in A which are not present in B. This leaves us with A-B={1} -

      If the question would have been B-A, then B-A ={8}

      Given Set A = {1,2,3,4,5,6} Set B = {2,3,4,5,6,7,8}

        you forgot '7' in your B-A calculation:

        B-A = {7,8}
