Hi there! You're doing great and your logic is spot on! However, it's checking the output and you've included two echo statements the challenge has not asked for. The challenge expects the output to be "9". But if you'll check your preview using this code, you'll see that you have the output "619".

Simply removing the first two echo statements and leaving the last echo statement in place solves this issue and your output will be as expected.

Hope this helps! :sparkles:

Thanks a lot Jennifer!

<?php
$integerOne = 1;
$integerTwo = 2;
$integerOne = $integerOne + 5;
$integerTwo = $integerTwo - 1;
$floatOne = 1.5;
 echo $integerOne * $floatOne;
?>

The code above works,. EDIT: just tested it, Task 3 doesn't pass for you because you have two echo's above the floatvalue, which modify the output and confuses the parser.
