Without changing the value of $integerOne or $floatOne, multiply $integerOne by $floatOne and display the results.

im not really sure what else to type. I've multiplied $integerOne by $floatOne but in my preveiw it states I've got the total of 619. i have no idea how i got that number

index.php
<?php

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



$integerOne += 5;
echo $integerOne;

$integerTwo -=1;
echo $integerTwo;

$floatOne = 1.5;


echo $integerOne * $floatOne;


?>

The preview screen shows all of the printed output. The 6 comes from you printing $integerOne and the 2 comes from printing $integerTwo. echo does not add spaces on it's own which is why it looks like one large number.

If you remove the first two echo statements in your code then you will be able to pass.
