task 3 $floatOne = 1.5; $integerOne = $integerOne * $floatOne; echo $integerOne;

index.php 
<?php

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

//task two

The questions states without changing the values of the variables.

You are changing the value of $integerOne $intergerOne used to equal 6 now it equals 9

<?php

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

//task two
  $integerOne += 5;
  $integerTwo -=1 ; //for some reason I don't think it likes --  use -=1 instead it might be because of the space $integerTwo-- might work but then again I don't think that's the way it's taught in the videos 

  echo $integerOne;
  echo $integerTwo;

//task 3
 $floatOne = 1.5;
 echo $integerOne * $floatOne; //only the results are printed the values of the variables haven't changed.
?>

Hope this helps

The challenge asks you to do this without changing the value of $integerOne. Echo the product of the multiplication directly 

<?php
echo $integerOne * $floatOne;
?>

You will also need to comment out or remove the echos from Task 2, as they will prevent Task 3 from passing if they are present.
