#include<iostream>
using namespace std;

{
    int A,B;
    cin >> A >> B;

    if(A > 1){
     if(B > 1){
      cout << A * B <<endl;
      }

      if(B = 1) {
       cout << A + B <<endl;
      }
     
      if(B < 1) {
       cout << A - B <<endl;
     }
}

      if(A = 0) {
       if(B >= 0){
       cout <<A + B <<endl;
       }
  
       if(B < 0){
       cout <<A - B <<endl;
       }

      if(A < 0) {
       if(B > 0) {
       cout << A + B <<endl;
