Hi Usman!

One tip: don't add any code that is not explicitly requested to pass the challenge.

The test programs are pretty rigid and unforgiving, unfortunately.

This passes all three tasks:

<?php

//Place your code below this comment

$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;

$integerOne += 5;
$integerTwo -= 1;

echo $integerOne * $floatOne;

?>

This passes, also:

<?php

//Place your code below this comment

$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;

$integerOne += 5;
$integerTwo -= 1;

$product = $integerOne * $floatOne; // using a variable
echo $product; 

?>

I hope that helps.

Stay safe and happy coding!

thanks
