63 is the result of mistakely adding 44 and subtracting 39 when you actually have to add 39 to this certain number and subtract 44. Find the result of the correct calculation.
63 44 [OP_SUB] 39 [OP_ADD] 39 [OP_ADD] 44 [OP_SUB]
var_a = 63
var_b = 44
var_c = var_a - var_b
var_d = 39
var_e = var_c + var_d
var_f = 39
var_g = var_e + var_f
var_h = 44
var_i = var_g - var_h
print(int(var_i))
