  • A = {a, b, c, d, e, f} 
    B = {e, f, g, h, j}

    a) A - B = {a, b, c, d, e, f} - {e, f, g, h, j}
                  = {a, b, c, d}

    b) B - A = {e, f, g, h, j} - {a, b, c, d, e, f}
                 = {g, h, j}

    c) ( A - B) ∩ A = {a, b, c, d} ∩ {a, b, c, d, e, f}
                           = {a, b, c, d}

    d) (A - B) ∪ (B - A) = {a, b, c, d} ∪ {g, h, j}
                                   = {a, b, c, d, g, h, j}
