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......
        numberMath(a,b);

    }

    public static void numberMath(int a,int b){

        if(a > b){

            System.out.println((a + b) + " " + (a - b) + " " + (a * b) + " " + (a / b) + " " + (a % b));
        }else{
            System.out.println((b + a) + " " + (b - a) + " " + (b * a) + " " + (b / a) + " " + (b % a));
        }
    }
}

这里为了方便阅读就是用了一个numberMath方法专门处理运算和输出。
