The syntax was wrong, but gave a "Something went wrong" error message instead of a "Try again" error message. The wrong error would make me think there was a bug with the program rather than my code was wrong.

    
    
function checkSign(num) {

return (num > 0)?"positive":(num === 0):"zero":"negative";

}
checkSign(10);

    ```
