// Defining the "calc" class
class calc {
var $number1;
var $number2;
function add($number1,$number2)
{
$result =$number1 + $number2;
echo "The sum of $number1 and $number2 is $result<br><br>";
echo "$number1 + $number2 = $result";
exit;
}
function subtract($number1,$number2)
{
$result =$number1 - $number2;
echo "The difference of $number1 and $number2 is $result<br><br>";
echo "$number1 &#045 $number2 = $result";
exit;
}
function divide($number1,$number2)
{
$result =$number1 / $number2;
echo "$number1 divided by $number2 is $result<br><br>";
echo "$number1 ? $number2 = $result";
exit;
}
function multiply($number1,$number2)
{
$result =$number1 * $number2;
echo "The product of $number1 and $number2 is $result<br><br>";
echo "$number1 x $number2 = $result";
exit;
}
function square($number)
{
$result = $number * $number;
echo "The square of $number is $result<br><br>";
echo "$number &#94; 2 = $result";
}
function squareroot($number)
{
$result = sqrt($number);
echo "The square root of $number is $result<br><br>";
}
function cube($number)
{
$result = $number * $number * $number;
