Yoongi wants to subtract 57 from a three-digit number. Yoongi misread the three-digit ones digit 9 as a 6. When Yoongi's car is 819, find the correct calculation result.
819 57 [OP_ADD] 6 9 [OP_SUB] [OP_SUB] 57 [OP_SUB]
var_a = 819
var_b = 57
var_c = var_a + var_b
var_d = 6
var_e = 9
var_f = var_d - var_e
var_g = var_c - var_f
var_h = 57
var_i = var_g - var_h
print(int(var_i))
