Need a while loop

Justin (14)
Cant figure out how to get the loop in my code, im using Win32 console app, in
C++

EDIT: NEED A DO WHILE LOOP


#include "iostream" 
#include "conio.h"
#include "string"

using namespace std;

int Addition(int x, int y);
int Subtraction(int x, int y);
int Division(int x, int y);
int Multiply2(int x, int y);

int main(){
	int num1;
	int num2;
	string mathType;
	cout << "Would you like to add, subtract, divide, or multiply : " << endl;
	cin >> mathType;
	cout << "Enter the first number you wish to " << mathType << ":" << endl;
	cin >> num1;
	cout << "Enter the second number you wish to " << mathType << ":" << endl;
	cin >> num2;
	system ("cls");

	if (mathType =="add"){
		cout << num1 << " + " << num2 << " = " << Addition(num1, num2) << endl;
	}
	if (mathType == "subtract"){
		cout << num1 << " + " << num2 << " = " << Subtraction(num1, num2) << endl;
	}
	if(mathType == "divide"){
		cout << num1 << " - " << num2 << " = " << Division(num1, num2) << endl;
	}
	if(mathType == "multiply"){
		cout << num1 << " * " << num2 << " = " << Multiply2(num1, num2) << endl;
	}
	_getch();

}

int Addition(int x, int y){
	int numAnswer;
	numAnswer = x + y;
	return numAnswer;
}

int Subtraction(int x, int y){
	int numAnswer;
	numAnswer = x - y;
	return numAnswer;
}

int Division(int x, int y){
	int numAnswer;
	numAnswer = x / y;
	return numAnswer;
}

int Multiply2(int x, int y){
	int numAnswer;
	numAnswer = x * y;
	return numAnswer;
}
