These are wrong:
16  (43) i got 59
156 98 i got : 58
192 47 i got: 145
The others are correct. 
16  (43) i got
16 + (43) = 27
156  98 i got
156 + 98 = 254
192  47 i got
192 + 47 = 239
0  (51) i got
o + 51 = 51
63 89 i got
63 + 89 = 152
12  (21) i got
12 + 21 = 9
92  (16) i got
92 + 16 = 108
72  15 i got
72 + 15 = 57
86  (19) i got
86 + 19 = 67
17  (46) i got
17 + 46 = 63
78  (53) i got
78 + 53 = 25 
did i get these right?
