Question regarding Challenge Task 3 of 3 PHP basics

These is my code leading up to my incorrect answer:

$integerOne=1; $integerTwo=2;

$integerOne=$integerOne+5; $integerTwo=$integerTwo-1; $floatOne=1.5;

When I type in the below section code for the final question it asks if I am sure I multiplied correctly; not sure what I did wrong.

var_dump ($integerOne * $floatOne);

index.php 
<?php

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

$integerOne=$integerOne+5;
  $integerTwo=$integerTwo-1;
$floatOne=1.5;
var_dump ($integerOne * $floatOne);



?>

Try echoing your result rather than using var_dump.
