This challenge is asking you to use a compound assignment operator to add/subtract the values from their respective variables (although, this is really not clear in the question...so I understand your confusion).

So, if the original setup had been "Create a variable named $floatOne and assign the value of 2.5 to it. Then add 4.5 to $floatOne.", your steps would have looked like:

(first part of challenge) $floatOne = 2.5;

(second part of challenge) $floatOne += 4.5;

Hope this helps.
