Problem Statement

Given an integer a as input, print the value a + a^2 + a^3.

Constraints

1 \leq a \leq 10

a is an integer.

Input

Input is given from Standard Input in the following format:

a

Output

Print the value a + a^2 + a^3 as an integer.

Sample Input 1

2

Sample Output 1

14

When a = 2, we have a + a^2 + a^3 = 2 + 2^2 + 2^3 = 2 + 4 + 8 = 14.

Print the answer as an input. Outputs such as 14.0 will be judged as incorrect.

Sample Input 2

10

Sample Output 2

1110

#include <bits/stdc++.h>

using namespace std;
typedef long long ll;

int main(void){
	cin.tie(0);
	ios::sync_with_stdio(false);

	ll N;
	int i,j;
	int tmp;
	int counter=0;
	ll answer=0;
	vector<int> given;

	cin >> N;

	
	answer=N + N*N + N*N*N ;
	cout << answer << endl;

	return 0;
