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 :)
