It is known that the sum of -a + (a) = 0.

Therefore, 
(a) the sum of 137 \; and \; -354
     = 137 + (-137) + (- 217)
     = - 217

(b) the sum of -52\; and\; 52
     =  -52 + 52 = 0

(c) the sum of -312,\; 39\; and\; 192
     = (- 231) + (81) + (39 + 192 )
     = (- 81) + (- 231) + (231)
     = - 81

(d) the sum of -50,\; -200\; and\; 300
      = - (50 + 200 ) + (300)
      = - 250 + (250) + 50
      = 50
