How to calculate access rights? How can I translate the right of this type "drwx------" into a numeric format (such as 777)?

Question

linux

There are permissions "drwx------", "drwxr-xr-x" . How can I make a folder with the same permissions? I would like to translate what I see in ls -ls into the form available to the chmod command?
