Multiplication Exercise

Create a New Float Variable named $floatOne with a value of 1.5. Without changing the value of $integerOne or $floatOne, multiply $integerOne by $floatOne and display the results.

In this case, the result will be either 1.5 or 9

both results are showing wrong. Whats the thing i am missing out

index.php 
<?php

//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;
$integerOne = $integerOne + 5;
$integerTwo = $integerTwo - 1;
$floatOne = 1.5;
var_dump  ($integerOne * $floatOne) ;

Hey Shouvik,

You're really close, but you're trying to use var_dump when you need to be using echo.

The following code will pass:

<?php

$integerOne = 1;
$integerTwo = 2;

$integerOne += 5;
$integerTwo -= 1;

$floatOne = 1.5;

echo $integerOne * $floatOne;

?>

You almost had it, great work :D

Good luck with the course!
