40 + 83 = 123
166
- 22 + (-83) + 5 = -22 - 83 + 5 = -100
82 + 83 + 94 = 259
36 + 47 = 83
6100000000 + 71000000 + 5100000 + 71000 + 83 = 6176171083
83/40 = 2.075 hours
this equals 818
It is: 97+83 = 180
-83 + 24 +(-19)= -102+ 24= -78
83 + 263 + 17 - 63 = 300
36 + 35 + 40 + 40 + 40 + 40 + 40 = 271 271 is the answer
37.4819
