At the first station where the train stops, 17 people got on and 29 got off. At the next station, after 27 people got off and 35 got on, I counted the number of people on the train, which was 116. How many people were on the train at first?
116 29 [OP_ADD] 17 [OP_SUB] 27 [OP_ADD] 35 [OP_SUB]
var_a = 116
var_b = 29
var_c = var_a + var_b
var_d = 17
var_e = var_c - var_d
var_f = 27
var_g = var_e + var_f
var_h = 35
var_i = var_g - var_h
print(int(var_i))
