step two of end of lesson exam and I cant get through. what am I doing wrong??

it wants me to add 5 to integer 1 and subtract 1 from integer two. this is how I wrote it and It wont pass me through. tried a few other ways too and nothing. is there a bug in the test or am I wrong? show me the right way anyone???

<?php

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

                                             /*I added this below to add to part one*/

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

There are two problems with your code:

  1. You're missing a semicolon after you declare $floatOne. This will cause a syntax error.
  2. You're var_dumping the result of the math. You need to actually change the value of the variables as shown below.
<?php
$number = 5;
$number = $number + 10;

Cheers :beers:

thanks a lot for the reply Greg! I took a break and started from scratch and was able to figure it out. and yes, that's exactly what I did wrong and had to do.
