How can i resolve that?

I plus 5 to the variable1 and then substract 1 to variable2, using var_dump, echo, reassing the value of the variables, and i don't know what to do

index.php 
<?php

//Place your code below this comment
$integerOne = 5;
$integerTwo = 1;

?>

Hey Cristian, The challenge here is to use arithmetic operators using the var_dump function.

If you add something like:

var_dump($integerOne += 5);
var_dump($integerTwo -= 1);

You should find success!

Let me know if you have any questions.
