1.   126 – ( 26 – 92 ) – ( – 108 )               35 -{ – 12 – [ -14 + ( -12)]}

   = 126 – 26 + 92 + 108                    = 35 + 12 + [ -14 + (-12)]

   = ( 126 – 26 ) + ( 92 + 108 )           =  35 + 12 + ( -14 ) + (-12)

   =  100 + 200                                  = [ 12 + ( -12)] + [ 35 + ( -14)]

   = 300                                             =    0 + 21

                                                         = 21

    -323 + [( – 847 ) + 564 -241]         [(-59) + 71] – [ – 83 – ( – 95)]

   = -323 + ( – 847) + 564 – 241       = (-59) + 71 + 83 +(-95)]

   = -323 + ( – 847) + 323                =  [( -59) + (-95)] + ( 71 + 83 )

   = ( 323 – 323 ) + ( -847)               =  (- 154) + 154

   = 0 + (-847)                                 = 0

   = -847

2. 126 – (26 – 92) – (-108)

   = 126 – 26 + 92 + 108

   = (126 – 26) + (108 + 92)

   = 100 + 200

   = 300

   35 – { – 12 – [ -14 + (-12)]}

   = 35 – {-12 + 14 + 12}

   = 35 – [ (12 – 12) + 14]

   = 35 – (0 + 14)

   = 35 – 14

   = 21

   _____________________________________

   -323 + [ (-847) + 564 – 241]

   = -323 + (-847) + 564 – 241

   = (564 – 241 – 323) + (-847)

   = 0 + (-847)

   = -847

   _______________________________________

   [(-59) + 71] – [-83 – (-95)]

   = (-59) + 71 + 83- 95

   = (71 – 59) – (95 – 83)

   = 12 – 12

   = 0
