There are four numbers: 10, 11, 12, and 13. What is the sum of the smallest number and the second smallest number?
[OP_LIST_SOL] 10 11 12 13 [OP_LIST_EOL] 1 [OP_LIST_MIN] 2 [OP_LIST_MIN] [OP_ADD]
var_a = 10
var_b = 11
var_c = 12
var_d = 13

if "/" in str(var_d):
    var_d = eval(str(var_d))
list_a.append(var_d)

list_a.reverse()
var_e = 1
list_b=list_a.copy()
list_b.sort()
