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

Solution in C (Clang 10.0.0) (judge verdict: Accepted)

	#include<stdio.h>
    #define 	ll 			long long
    #define 	w(t)		int t; cin>>t; while(t--)  
	#define 	AsmShuvo()  ios_base::sync_with_stdio(0);cin.tie(0);cout.tie(0);
			
    int main()
    {
    //AsmShuvo()
    	
    	int a;
    	scanf("%d", &a);
    	int x = a+a*a+a*a*a;
    	printf("%d", x);
		
     	return 0;
