Here is my code for calculator class which have 4 function, add,subract,multiply and divide. which take s two input . I want to make a class than can accept more than 2 input and return answer. I am using laravel for making this calculator.

This is my controller method 

 public function calculate()
    {
        $oprator;
        $input = Input::get('ans');
        $logs = new Log;
        $logs->user_id = Auth::id();
        $logs->log_data = $input;
        preg_match_all('/\d+/', $input, $matches);
        if (preg_match('/[\/\'^£$%&*()}{@#~?><>,|=_+¬-]/', $input,$oper))
        {
            $oprator = $oper[0];
        }

       $firstnumber = $matches[0][0];
       $secondnumber = $matches[0][1]; 

       $Maths1= new Maths();
        if($oprator == "+"){ 
            $data=array('answer'=> $Maths1->add($firstnumber,$secondnumber));
            $logs->log_answer = $data['answer'];
            $logs->save();
        return view('calculator',compact('data'));
        } 
        if($oprator == "-"){ 
          $data=array('answer'=> $Maths1->subtract($firstnumber,$secondnumber));
          $logs->log_answer = $data['answer'];
            $logs->save();
        return view('calculator',compact('data')); 
        } 
        if($oprator == "/"){ 
          $data=array('answer'=> $Maths1->divide($firstnumber,$secondnumber));
          $logs->log_answer = $data['answer'];
            $logs->save();
        return view('calculator',compact('data')); 
        } 
        if($oprator == "*"){ 
          $data=array('answer'=> $Maths1->multiply($firstnumber,$secondnumber));
          $logs->log_answer = $data['answer'];
            $logs->save();
        return view('calculator',compact('data'));
        }
    }

}

Here is the oop Maths class for calculation

<?php 

namespace App\Custom;     
 class Maths{


         public  function add($number1,$number2) 
          { 
                   $result =$number1 + $number2; 
                    return $result; 
           } 

          public  function subtract($number1,$number2) 
          { 
                   $result =$number1 - $number2; 
                    return $result;
           } 

          public  function divide($number1,$number2) 
          { 
                   $result =$number1 / $number2; 
                    return $result; 
           } 

          public  function multiply($number1,$number2) 
          { 
                   $result =$number1 * $number2; 
                    return $result;
           } 
}

Here is my view calculator.blade,php
