Yoongi wants to add a three-digit number and a two-digit number. Yoongi mistakenly thought the 9 in the unit digit of a three-digit number was 6, and by changing the tens and unit digits of a two-digit number, he mistakenly thought it was 23. When the sum obtained by Yoongi is 299, find the three-digit number.
299 23 [OP_SUB] 6 9 [OP_SUB] [OP_SUB]
var_a = 299
var_b = 23
var_c = var_a - var_b
var_d = 6
var_e = 9
var_f = var_d - var_e
var_g = var_c - var_f
print(int(var_g))
