There are a total of 60 marbles in the bag. There are 32 black marbles, 10 red marbles, and 5 green marbles. If the marbles in the bag are black, red, green, and white, how many white marbles are there?
60 32 [OP_SUB] 10 [OP_SUB] 5 [OP_SUB]
var_a = 60
var_b = 32
var_c = var_a - var_b
var_d = 10
var_e = var_c - var_d
var_f = 5
var_g = var_e - var_f
print(int(var_g))
