<?php

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

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

var_dump ($integerOne*$floatOne);

echo "Display = "; echo $integerOne; echo " First : "; echo $floatOne; echo " Second";

//please tell me what's the issue :( ?>

index.php 
<?php

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

$integerOne = $integerOne + 5;

Hi Patrick,

You have the sum correct, you just don't have to do anything fancy with the displaying of the answer. Instead of using a var_dump and several echo statements, just directly echo out the sum that you've used inside the var_dump and it will pass the challenge.

You are nearly at the answer.

You have 2 choices either change the 'var_dump' to an echo like suggested above

Or you can do this

Add a new variable for example called result and initialize it to 0 like this

$result =0;

Then assign the value of the multiplication and store it in this variable so 'var_dump' becomes

$result = (integerOne * floatOne);

Then simply echo the variable

echo $result;

And it should display a value of 9 and pass the test

<?php

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

$result = 0;

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

$result = ($integerOne*$floatOne);

echo $result;

?>
