import java.util.Scanner;

// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int a = in.nextInt();
        int b = in.nextInt();
        int dif = Math.abs(a - b);
        int max = a > b ? a : b;
        int c = max + dif;
        System.out.println(c);

    }
