Write a Calculator class that can accept two values, then add them, subtract them, multiply them together, or divide them on request. For example: $calc = new Calculator( 3, 4 ); echo $calc- >add(); // Displays “7” echo $calc- >multiply(); // Displays “12”

Calculate.html
<HTML><BODY>
<FORM method=get action="Calculate.php">
Enter first value: <INPUT type=text name="a"><br>
Enter second value:<INPUT type=text name="b"><br>
<INPUT type=submit value=”Calculate”>
</FORM></BODY></HTML>
Calculate.php
<?php
class Calculate
      {public $a;
public $b;
function __construct($a,$b){
$this->a=$a;
$this->b=$b;
}
public function add()
         {
          $c=$this->a+$this->b;
echo"Addition = $c<br>";
         }
public function subtract()
         {
          $c=$this->a-$this->b;
echo"Subtract = $c<br>";
         }
public function multiply()
         {
          $c=$this->a*$this->b;
echo"Multiplication = $c<br>";
         }
public function div()
         {
          $c=$this->a/$this->b;
echo"Division = $c";
         } }
$x=$_GET['a'];
$y=$_GET['b'];
$calc=new Calculate($x,$y);
$calc->add();
$calc->subtract();
$calc->multiply();
$calc->div();?>
