I mistakenly subtracted a number that should be multiplied by 423, and I got 421. Find the value of subtracting 500 from the sum of the correctly calculated and incorrectly calculated values.
421 423 423 421 [OP_SUB] [OP_MUL] [OP_ADD] 500 [OP_SUB]
var_a = 421
var_b = 423
var_c = 423
var_d = 421
var_e = var_c - var_d
var_f = var_b * var_e
var_g = var_a + var_f
var_h = 500
var_i = var_g - var_h
print(int(var_i))
