The variable name always has to come first.

It should say:

$results = $integerOne * $floatOne;

Hello Austin,

Your method is a valid one, however you accidentally placed the variable $results at the wrong end of the statement (see below):

$results = $floatOne * $integerOne;
echo $results;

This works fine, but I simply echoed the entire statement like this:

echo $floatOne *  $integerOne;

Hope this helps :)
