import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int a = scanner.nextInt();
        int b = scanner.nextInt();
        scanner.close();

        //write your code here......
        int he = a + b;
        int cha = a > b ? a - b : b - a; //三元运算符
        int ji = a * b;
        int shang = a > b ? a / b : b / a;
        int mo = a > b ? a % b : b % a;
        System.out.print(he + " " + cha + " " + ji + " " + shang + " " + mo);

    }
}

1. 三元运算符：<条件表达式> ? 表达式1 : 表达式2
2. 如果条件表达式为true，则执行表达式1的结果
3. 如果条件表达式为false，则执行表达式2的结果
