  1. a) [154-(36-33)^3.2]-17
    = [154-3^3.2]-17
    = [154-27.2]-17
    = [154-54]-17
    = 100-17
    = 83
    b) [(-29)+(-19)]+(-22)
    = -48+(-22)
    = -70
     

  2. a,
    [ 154 – ( 36 – 33 )^3. 2 ] – 17
    = [ 154 – 3^3. 2 ] – 17
    = [ 154 – 27. 2 ] – 17
    = [ 154 – 54 ] – 17
    = 100 – 17
    = 83
    b,
    [ ( -29 ) + ( -19 ) ] + ( -22 )
    = [ -29 – 19 ] – 22
    = -48 – 22
    = -70
