Is there something that can turn file permissions display into numeric?

OK, when I use ls -l I get the list of files and folders but also a list of permissions, unless I have a printed out table of what they mean when choosing a chmod value, I have absolutely no idea what they are, is there a command that I can use that will show the permissions in numeric form?

For Example this bash file in my user directory

-rwxr--r-- 1 usalabs usalabs 237 Aug 24 06:20 start-irc.sh

I would like it to show a number instead of all that xyz crap, that is not understandable.
