Multiplying Two variables

I don't understand what I am doing wrong, I have multiplied it, I used the echo function and I don't have any spelling error.

index.php 
<?php

$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;
echo $integerOne * $floatOne;
$integerOne += 5;
var_dump ($integerOne);

$integerTwo -= 1;
var_dump ($integerTwo);

echo $integerOne * $floatOne;




?>

The only way I could reproduce that error was with the two echo statements. The following passed for me:

<?php

$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;
$integerOne += 5;
$integerTwo -= 1;

echo $integerOne * $floatOne;

?>

The error message received is: Make sure you use "echo" instead of "var_dump"

Remove the var_dumps and the first echo statement

I have just done that and this is the error that it is giving me. "Bummer: Are you sure you multiplied $integerOne by $floatOne? This should be the same as 6*1.5 which equals 9."
