I don't see where did I make a mistake. Can you help me?

I can't pass the quiz as I don't see where I did an error. To me, I have followed correctly instructions made in the video.

index.php 
<?php

//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;

$integerOne += 5;
--$integerTwo;

$floatOne = 1.5;
$result = $integerOne * $floatOne;

var_dump($result);

?>

In php, does not use "+=" instead it uses ".=" and in my expierence has only worked on strings.

Instead use $integerOne = $integerOne + 5; I know it seems kinda long, but it works :)

<?php
//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;

$integerOne = $integerOne + 5;
$integerTwo--;
?>
