Front End Web Development Techdegree Student 6,520 PointsWithout 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
<?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;
?>

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.
