php Function Parameters question?

Here's my hw directions:

* Write an entire function named Sub_5
* It has an input parameter named $invalue, subtract 5 from the parameter $invalue
* Return the calculated value (i.e. the result of the subtraction)
* You do not have to call Sub_5, I will do that.

This is the code I did that says it was wrong:

function Sub_5 ( $invalue-5 ) {

return $invalue;
} // end of Sub_5

What did I do incorrectly? Thanks
