  1.   ( -2 )^5 + [ ( -69 ) : 3 + 53 ) ]. ( -2 ) – 8
    = -32 + [ -23 + 53 ]. 2 – 8
    = -32 + 30. 2 – 8
    = -32 + 60 – 8
    = 28 – 8
    = 20
     

  2. ( -2 )^5 + [ ( -69 ) : 3 + 53 ) ] . ( -2 ) – 8
    = -32 + [ ( -23 ) + 53 ) ] . ( -2 ) – 8
    = -32 + 30 . ( -2 ) – 8
    = -32 + ( -60 ) – 8
    = -92 – 8
    = -100
