How should I subtract 1 from integer two in this example?
<?php //Place your code below this comment $integerOne= 1; $integerTwo= 2; $floatOne = 1.5; $integerOne += 5 ?>

You are on the right track with the addition of 5 to $integerOne. Just add a semi-colon and that line will work.
For the subtraction you do just like you did with the addition but change the sign to subtraction and the number to "1":
//Place your code below this comment $integerOne = 1; $integerTwo = 2; $floatOne = 1.5; $integerOne +=5; $integerTwo -=1; ?>
Hope this helps and happy coding!
