    a)
    ( 2354 – 45 ) – 2354
    = 2354 – 45 – 2354
    = -45
    b)
    ( – 2009 ) – ( 234 – 2009 )
    = – 2009 – 234 + 2009
    = -234
    c)
    (16 + 23 ) + ( 153 – 16 – 23 )
    = 16 + 23 + 153 – 16 – 23
    = 153
    d)
    ( 134 – 167 + 45 ) – ( 134 + 45 )
    = 134 – 167 + 45- 134 – 45
    = -167
    e)
    – 3752 – ( 29 – 3632 ) – 51
    = – 3752 – 29 + 3632  – 51
    = -200
    f)
    321 + { -15 + [ 30 + ( – 321 ) ] }
    = 321 + [ -15 + ( 30 – 321 ) ]
    = 321 + ( -15 + 30 -321 )
    = 321 – 15 + 30 – 321
    = 15
