PHP PHP Basics Unit Converter Manipulating Numbers

I do not know how to do this at all. I tried several things and watched the video and took notes several times.

var_dump($integerOne * $floatOne); and echo $integerOne * $floatOne = "; and echo $integerOne; echo $floatOne; var_dump($integerOne * $floatOne);

index.php
<?php

//Place your code below this comment
$integerOne = 1;
$integerOne = $integerOne + 5;
$integerTwo = 2;
var_dump($integerTwo--);
$floatOne = 1.5;
?>
