Hi Gary,

For this task, you have to write the value to the variable. The correct way to do this is as follows:

$integerOne = 1;
$integerTwo = 2;

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

You would use '+' and '-' in a situation like this, for example:

$integerOne = 2; 
$integerTwo = 4; 

echo $integerOne + $integerTwo;

Good luck. :)

You aren't changing the values of $integerOne and $integerTwo. To change them, you need to say that they are equal to themselves, followed by the addition and subtraction you have defined. Like this:

          <?php

//Place your code below this comment

//Task 1 of 3
$integerOne = 1;
$integerTwo = 2;

//Task 2 of 3
$integerOne = $integerOne + 5;
$integerTwo = $integerTwo -1;

//Task 3 of 3
$floatOne = 1.5;
$result = $integerOne * $floatOne;
echo $result;

?>
          ```
