you need to call the function then pass 1 into it as an argument so that the parameter num will become 1 then it will output 11.

<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
<script src="script.js">

add10(1);

</script>
</body>
</html>

you can test your code in the console of Chrome / Firefox

thanks
