you can do the following when adding or subtracting to another variable with += or -= operators;

$integerTwo = 2;
$floatOne = 1.5;

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

$multiply = $integerOne * $floatOne;

echo $multiply;

That is a lot simpler then what I was thinking.

no problem at all, the challenges are sometimes confusing, which I think they should be reworded in ways :)
