I decided to share 1 liter (L) of milk with my friends. Of these, Myeongseok drank 0.1 liters (L), and Mingu drank 0.2 liters (L) more than Myeongseok. After a while, if Min-jae came and drank 0.3 liters (L) of milk, how many liters (L) of milk could I drink?
1 0.1 [OP_SUB] 0.1 0.2 [OP_ADD] [OP_SUB] 0.3 [OP_SUB]
var_a = 1
var_b = 0.1
var_c = var_a - var_b
var_d = 0.1
var_e = 0.2
var_f = var_d + var_e
var_g = var_c - var_f
var_h = 0.3
var_i = var_g - var_h
print('{:.2f}'.format(round(var_i+1e-10,2)))
