import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Solution {
    public static void main(String[] args) throws Exception {
        BufferedReader r = new BufferedReader(new InputStreamReader(System.in));
        //
        int sum = 0;
        for(; ;){
            String name = r.readLine();
            if(name.equals("сумма")) break;
            else {
            int i = Integer.parseInt(name);
            sum = sum + i;}

        }
        System.out.println(sum);
        //напишите тут ваш код
    }
