Step 1: Codes for Index.php

HTML codes top of the page

<html>
<head>
<title>Working with Method and Object in PHP OOP</title>
</head>
<form method="POST" action="">
<span>Enter First Number:</span><br/>
  <input type="number" name="num1" required/><br >

Add the below php codes end of the html

<?php
include("function.php");
if(isset($_POST["submit"])){
 $numOne=$_POST['num1'];
