Function Return

In one of the questions of the Quiz:

function sum_two_numbers ($one,$two){
    $sum = $one + $two;
    return $sum;
}
sum_two_numbers(1,5);

I Selected 6, but is wrong. Is there something i didnt notice?

The questions asks what does this code displays, and they only call the function but never print the result. Therefore the result is actually 6 as you mention but the code displays Nothing.

Hope it helps
