I think it is that you are adding 5 to integerOne before multiplying, the instruction only want you to multiply the two variables trying getting rid of that part and re-trying the test.

You're setting $integerOne when you are multiplying $integerOne*$integerTwo. Either display that calculation directly, or create another variable.
