php integer. I have to add 5 to $integerOne. I have done this and it says I have not, despite the answer being correct

what am I missing?

index.php 
<?php

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

var_dump ($integerOne +5);
var_dump ($integerTwo -1);
?>

I think it actually wants you to reassign the new value to $integerOne like so

$integerOne += 5;

Since you're not actually storing the value, when the Challenge checks $integerOne and expects to see 6 it's still returning 1
