Manipulating numbers

I'm stuck on php track task:

Create a New Float Variable named $floatOne with a value of 1.5. Without changing the value of $integerOne or $floatOne, multiply $integerOne by $floatOne and display the results.

If i type the code below, it says something like: "are you sure you multiplied correctly?".

<?php

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

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

$floatOne = 1.5; var_dump($integerOne * $floatOne);

?>

If i delete "$integerOne += 5; $integerTwo -= 1;" part, task 2 doesn't pass (It is a 3 task challenge).

Any help would be appreciated.

index.php 
<?php

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

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

$floatOne = 1.5;
var_dump($integerOne * $floatOne);
?>

You've got the right idea. Is there any reason you are using var_dump instead of echo?

Hey Marin,

I just completed this one like this:

<?php

$integerOne = 1;
$integerTwo = 2;

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

$floatOne = 1.5;

echo $integerOne * $floatOne;

Hope that helps,

Thanks,

Ben
