Does this code not change the value of IntegerOne ? var_dump($integerOne + 5);

The compiler says the value of integerOne hasn't been changed, yet I've gone back over the tutorials and repeated what was done there but my code doesn't work. Don't understand why ? Thanks

index.php 
<?php

//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;
var_dump($integerOne + 5);
var_dump($integerTwo - 1);
?>

Try this code instead:

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

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