Where am I wrong? "Multiply $integerOne by $floatOne and display the results."

My code:

<?php

//Place your code below this comment

$integerOne = 1; $integerTwo = 2; $floatOne = 1.5;

echo $integerOne = $integerOne + 5; echo "<br>"; echo $integerTwo = $integerTwo - 1; echo "<br>"; $res = $integerOne * $floatOne;

print($res);

?>

index.php 
<?php

//Place your code below this comment

$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;

echo $integerOne = $integerOne + 5;
echo "<br>";
echo $integerTwo = $integerTwo - 1;
echo "<br>";
$res = $integerOne * $floatOne;

print($res);

?>

Hi there! You're doing terrific! You really are, but the previous two tasks didn't ask you to print anything. They only asked you to change the values. You went ahead and printed them and even formatted them nicely and everything! But this causes a problem when you get to step three as it is only expecting to see the number "9" printed to the page, but you have 6 1 9 printed there instead. Removing the additional echo statements causes this to pass all 3 steps so well done!

Hint :bulb: On these challenges, it's a great idea to try not to do anything the challenge hasn't asked for. Even if functional outside the challenge, it can cause the challenge to fail.

Hope this helps! :sparkles:

I got stuck on this as well. Is there a reason why the questions aren't progressive? The math from previous questions was required to make the question work, but we were only supposed to echo the last line. If that isn't said, how do you expect us to answer it? I worked on it for a long time -getting the correct answer and just got frustrated because I knew I was writing it correctly.

I'm trying to learn the code I should also have to try to learn how to get around your poorly worded questions.
