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.

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) ;

?>

Hi there,

It looks like you've got the right code, you just need to echo the results to display it to the screen rather than using a var_dump

<?php

//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;
$integerOne = $integerOne + 5;
$integerTwo = $integerTwo - 1;
$floatOne = 1.5;
echo $integerOne * $floatOne;

?>

var dump will display certain properties of variables rather than the output itself. :-)

Change the var_dump to echo.
