Some help here, I can see what I am doing wrong

I have tried many versions of this, what am I missing?

script.js 
function add10(num){
        var num = add(add10, 10);

    return num();

};
index.html 
<!DOCTYPE HTML>
<html>

"num", isn't a function, so you just need to return it as a variable on its own with no parentheses.

At some point, you will need to call the function, which you do below the function itself.

So what you need to do is use the return statement to calculate `num with the number 10

And then call the function with the number you want to go with the num` variable.
