You need to add 5 to $integerOne and Subtract 1 from $integerTwo. actually you don't need to log the result all you have todo is add 5 into $integerOne and Subtract 1 from $integerTwo.

Here's my solution

<?php

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

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

?>

If you're not familiar with += and -= it's equivalent to $integerOne = $integerOne + 5 and $integerTwo = $integerTwo - 1.
