You can work with natural logs by pressing the "LN" button, which is located 3 rows up on the leftmost column. Ln represents #log_e# by default, so you shouldn't need to do any other tinkering there.

You can also work with the natural base #e# by hitting 2nd and then the division key, or by hitting 2nd and then LN, which will give you an #e^x# power (you can replace #x# with whatever you want).

Hope that helped :)
