Simple question: How do I add 5 to an integer?

I can't get past this question. I have tried multiple things. I think I am making it too hard, but can't get my brain to go back now.

index.php 
<?php

//Place your code below this comment
$integerOne = 1; 
$integerTwo = 2;
$floatOne = 1.5;

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

👋 Jennifer Klakulak,

You were very close because both of your var_dumps had the correct logic inside. To expand on the Robert's correct answer, all you needed to do is assign the correct variable names to the logic you used, like this:

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