Help With Php Foreach

Here's the question: Next, modify the code inside the foreach loop to display the $isbn in parentheses. After the title, add a space, an opening parenthesis, the ISBN, and a closing parenthesis.

Here's my code

<ul>

        <?php foreach($books as $isbn => $book) { ?>

            <li><?php echo $book ($isbn); ?></li>

        <?php } ?>

    </ul>

I think they want this:

    <?php foreach($books as $isbn => $book) { ?>

        <li><?php echo $book . ' (' . $isbn . ')'; ?></li>

    <?php } ?>
