Yoongi tried to add a three-digit number to 57. Yoongi misread the 9 in the ones in the three-digit number as 6. When the sum obtained by Yoongi was 823, find the correct calculation result.
823 57 [OP_SUB] 6 9 [OP_SUB] [OP_SUB] 57 [OP_ADD]
var_a = 823
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))
