Hey Buddy; I think I know what the problem is. When the natural log is written down for example, the natural lof of 6; is written down ln 6. Your calculator works differntly. You must type the number first then "ask it" what the natural log is, by pressing ln. So number first; ln button second. Good luck
To use Natural Log on the Scientific Texas Instruments, you may need to enter your number first (which is counter-intuitive). E.g. ln 1, press "1" first, and then the LN key.
The button itself is right beside the OFF button. To access the "e to the x" (notice written in yellow just behind it) you would need to hit the 2ND button first.
