Answer to a code challenge

I cant figure out how to multiply the integer and the float and then displaying the answer using echo. I have tried everything and its still not working. Thank You!

index.php 
<?php

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

$integerOne = $integerOne + 5;
var_dump( $integerOne);

$integerTwo = $integerTwo - 1;
var_dump( $integerTwo);

$floatOne = 1.5;
$a = $integerOne * $floatOne;
 echo $a;



?>

Hi Vince,

Is it giving you an error message saying "Make sure you use "echo" instead of "var_dump""? Try removing your var_dump statements.

It's also possible to perform the calculation directly in the echo statement rather than declaring a new variable. e.g. echo $integerOne * $floatOne; (saves having to declare a new variable).
