index.php 
<?php

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

$floatOne = 1.5;

?>

👋 Josie Fisher,

First, you need to create three variables: $integerOne, $integerTwo and $floatOne respectively. It seems like you got that part. The next two sections use the variables you created to perform simple math operations, like this: 

$a = 1;
$b = 2;
$c = 1.5;
// Math operations using variables
$a = $a + 5;
// To subtract replace the + for a -

I hope this was enough of a clue to solve this challenge. Happy coding! 🙌

//Place your code below this comment
$integerOne = 1;
  $integerTwo = 2;
  $floatOne = 1.5;

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