# Arithmetic Calculator challenge problem, I cant exit the program for some reason.

Hi, This is my code:

```using System;

namespace TreeHouse.Calculator
{
class Calculator
{
static void Main()
{
var totalResult = 0.0;

while(true)
{
try
{
var number = double.Parse(entry);
if(entry.ToLower() == "quit") {
break;

}

Console.WriteLine("Please enter an operation [+ - / * ]: ");
if(entry2.ToLower() == "quit") {
break;
}

var number2 = double.Parse(entry3);
if(entry3.ToLower() == "quit") {

break;
}

if(entry2 == "+")
{
totalResult = number + number2;
}

else if(entry2 == "-")
{
totalResult = number - number2;

}

else if(entry2 == "*")
{
totalResult = number * number2;

}
else if(entry2 == "/")
{
totalResult = number / number2;

}

Console.WriteLine("the result is: {0}", totalResult);

}

catch(FormatException) {
continue;

}

}

}

}

}
```

when i try to exit the program by typing 'quit', i get the messege from my exception, I checked alot of times and i can't find the problem why my 'if' statment are not working..

another problem i have is when i type a string or a number in a operator prompt it pass and in result the "final result" become 0.. any ideas how to fix this?

:D?

****** UPDATE ******

I somehow tried to get all this code outside the 'try' check

```using System;

namespace TreeHouse.Calculator
{
class Calculator
{
static void Main()
{
var totalResult = 0.0;
Console.WriteLine("what is your name? : ");
Console.WriteLine("Welcome to the program {0}!", name);

while(true)
{
if(entry.ToLower() == "quit") {
Console.WriteLine("Goodbye, {0}", name);
break;

}

Console.WriteLine("Please enter an operation [+ - / * ^ ]: ");
if(entry2.ToLower() == "quit") {
Console.WriteLine("Goodbye, {0}", name);
break;
}

if(entry3.ToLower() == "quit") {
Console.WriteLine("Goodbye, {0}", name);
break;
}

try
{
var number = double.Parse(entry);
var number2 = double.Parse(entry3);

if(entry2 == "+")
{
totalResult = number + number2;
}

else if(entry2 == "-")
{
totalResult = number - number2;

}

else if(entry2 == "*")
{
totalResult = number * number2;

}
else if(entry2 == "/")
{
totalResult = number / number2;

}

else {
totalResult = Math.Pow(number, number2);

}

Console.WriteLine("the result is: {0}", totalResult);

}

catch(FormatException) {
continue;

}

}

}

}

}
```

It's working now but i dont fully understand why i had to get this code outside of the "TRY" check.

and i still didnt fixed the other problem i mentioned before. The reason are the following codes

```                   Console.WriteLine("Please Enter a number: ");
var number = double.Parse(entry);
if(entry.ToLower() == "quit") {
break;

}
