What is the exact error message you get? Did you tried to echo both numbers?

You need to do the operations in two step: Initialization and Update =>

<?php

$integerOne = 1;
$integerOne = $integerOne + 5;

?>

Nope, won't work with this challenge. The challenge is based on a specific method to do the operations.

EDIT : But your code is actually valid =)

$integerOne = 1; $integerOne +=5; $integerTwo = 2; $integerTwo -=1;
