Error in my Calculator in unity

I trying to create calculator here, however it can only calculate 1 digit number. When I try 2 digits number it's calculate wrong. For example, I tried 11+1 but the answer is 2.

Code (CSharp):

1. using System.Collections;
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6. using UnityEngine.EventSystems;
7.  
8. public class Calculator : MonoBehaviour

15.     string operatorSymbol;
16.     int i = 0;
17.     int result;
18.     bool displayerResults = false;
19.     public void ButtonPressed()
20.     {
21.         if(displayerResults == true)
22.         {
23.             inputField.text = "";
24.             inputString = "";
25.             displayerResults = false;
26.         }
27.         string buttonValue = EventSystem.current.currentSelectedGameObject.name;
28.         inputString += buttonValue;
29.  
30.         int arg;
31.         if (int.TryParse(buttonValue, out arg))
32.         {
33.             if (i > 1) i = 0;
34.             number[i] = arg;
35.             i = i + 1;
36.         }
37.         else
38.         {

Oh it's still doesn't work, all I want is to make 10+1= 11. and other more than 2 digits number working correctly in what it should be.

 

Actually i didn't do any thing, but i made the first reply to correct the formatting of the code so i can read it and help you.
your problem is that the code does not allow you to store two digits integer, why????
Because every time you press on a digit you immediately store it in the array (in line 32 to line 34), so if you want to type 11, will press 1 and your code will store that 1 in the first index in the array, then you press 1 again and the code will store it in second index of the array.
that will end up having an array like this:

Code (CSharp):

1. number[0] = 1;
2. number[1] = 1;

that's why you get answer equals to 2.

To solve this, you should only store the integer after you press on operator symbol.
declare the number array as public

public int[] number;

so you can see it in the inspector.

 

Now everytime I press it is equal to zero so which correct line I should declare the integer (line from my old code)

below my new code with new error.
