Put two number of cards that marked 10, 30, 50 each into a box and draw 3 of them to find the sum. How many different sums can there be?
[OP_LIST_SOL] 10 30 50 [OP_LIST_EOL] [OP_LIST_LEN] 2 [OP_MUL] 3 [OP_COMB]
var_a = 10
var_b = 30
var_c = 50
list_a= []
if "/" in str(var_c):
    var_c = eval(str(var_c))
list_a.append(var_c)
if "/" in str(var_b):
    var_b = eval(str(var_b))
list_a.append(var_b)
if "/" in str(var_a):
    var_a = eval(str(var_a))
list_a.append(var_a)
list_a.reverse()
var_d = len(list_a)
var_e = 2
var_f = var_d * var_e
var_g = 3
var_h = 1
var_f = int(var_f)
var_g = int(var_g)
for i, elem in enumerate(range(var_g)):
    var_h = var_h * (var_f-i)
for i, elem in enumerate(range(var_g)):
    var_h = var_h / (i+1)
print(int(var_h))
