Multiply $integerOne by $floatOne and display the results.

i am on the section of variables and numbers, now with integers i thought we used var_dump but it is saying use echo, please assist

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);

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

?>

nothing wrong with the code nor the logic, just that, you have to be well aligned, with the question that they have raised, so I'd say take off all the unwanted code here I would omit the first 2 var_dump, as that was never asked then, replace the required one with an echo, replacing the var_dump

now try

<?php
$integerOne = 1;
$integerTwo = 2;

$integerOne = $integerOne + 5;

$integerTwo = $integerTwo - 1;


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