Front End Web Development Techdegree Student 21,661 Pointswhich one is the argument?
I am stuck on a question which ask, what are the argument
function sum_two_numbers($one,$two) {
$sum = $one + $two;
return $sum;
}
$x = sum_two_numbers(1,5);
IMO, the argument is what is inside the brackets, but the quiz doesn't give me option. Instead it says in option either $one , $sum , $x.

Treehouse TeacherFor this challenge, they are expecting $one and $two as arguments. I would however argue that these are the parameters while the arguments would be 1 and 5. But it's semantics

Arguments are external values that your function will work with, like in a mathematical function, f(x), x is the argument, because the value of the function varies according to the value of x.

Treehouse Teacher@Anmar Khan then in that case the "arguments" would be $one and $two.

Treehouse TeacherAmmar Khan Not according to the question I'm looking at. The choices I'm presented are $one, $sum, $x, and "All three are considered arguments". In this case, the answer is $one.
