Step 1: 5 —the natural logarithm of 5 is calculated and displayed in history.

Step 2: – π is entered as a divisor and applied to the previous result.

You select your preferred entry method from page 1 of the Home Settings screen ( ). Select

settings as normal.

RPN is available in Home view, but not in CAS view.

The same entry-line editing tools are available in RPN mode as in algebraic and textbook mode. You can edit

an expression on the entry line using the following keys:

●

Press to delete the character to the left of the cursor.

●

Press to delete the character to the right of the cursor.

●

Press to clear the entire entry line.

If there is no expression on the entry line, you can press to clear the entire history.

History in RPN mode

The results of your calculations are kept in history. This history is displayed above the entry line (and by

scrolling up to calculations that are no longer immediately visible). The calculator oers three histories: one

for the CAS view and two for Home view. The two histories in Home view are:

●

non-RPN—visible if you have chosen algebraic or textbook as your preferred entry technique

●

RPN—visible only if you have chosen RPN as your preferred entry technique. The RPN history is also

called the stack. As shown in the following illustration, each entry in the stack is given a number. This is

the stack level number.

As more calculations are added, an entry’s stack level number increases.
