Multiply $integerOne by $floatOne and display the results.

Why is this code:

<?php

//Place your code below this comment

$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;

echo $integerOne += 5;
echo $integerTwo -= 1;
echo ( $integerOne * $floatOne );

?>

Showing me this error: Bummer: Are you sure you multiplied $integerOne by $floatOne? This should be the same as 6*1.5 which equals 9.?

On preview I can see the results are 6 1 9

Only the instructions for task 3 include "display the results". The other two instructions ask you to change the values but not to display them.

So when you get to task 3, the system is expecting to see "9", but this code is giving it "619" instead.

Also, for any future questions it would be helpful if you provide a link to the lesson, quiz or challenge. You might want to take a look at this video about Posting a Question.
