To add a value to a variable you need to use the concatenation sintax, which is '+=' instead o just '+'.

The code under should work fine.

<?php

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

$floatOne = 1.5;

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

the problem you have having are you getting PHP to do the sum but you are not telling PHP where to put the result, this can be done in two ways the fist is $thing5 = 2 + 3; and the second is $inc += 5
