There are a total of 3 trains at the train station. Each train has 12 cars, and each car has the same number of seats with 24. Find the number of all seats on the trains at the station.
3 12 [OP_MUL] 24 [OP_MUL]
var_a = 3
var_b = 12
var_c = var_a * var_b
var_d = 24
var_e = var_c * var_d
print(int(var_e))
