13,937 PointsHow am I supposed to add to $integerOne without changing task 1?
I tried var-dump to add both numbers but the Bummer! warning says that I did not change the $integerOne. This is confusing because when I try something to add to $integerOne other than var-dump I get a message that task one is no longer passing. I watched the videos twice and do not understand what the task is looking for.
<?php
//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;
var_dump( 5 + $integerOne);
var_dump( $integerTwo - 1);
?>

First, you don't need to use var_dump. This function does not alter anything. It is simply used to print data. The challenge will always give a Bummer if you add (or delete) code that was not asked for in the instructions.
Now, for the second task, all you need to use is a combined operator. Combined operators take a variable and re-assigns a new value based on the combined operator and value used. Alena gives an example of this for adding to a variable in this video starting at ~4:58.
Hope this helps. :)
