public class Main {

    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        int a,b,c;

        a = sc.nextInt();
        b = sc.nextInt();

        c = a+b;

        System.out.println(c);
    }
}

        String str = br.readLine();
        StringTokenizer st = new StringTokenizer(str," ");
        int a = Integer.parseInt(st.nextToken());
        int b = Integer.parseInt(st.nextToken());
