Using INPUT for ENTER and for R. Except in CFLO and SUM lists, the Ikey also performs the Efunction and the ]key also performs the ~function.

!In lists: I stores numbers. Use = to enter numbers into the stack during arithmetic calculations.

!In lists: [and ]move through lists. Use ~to roll through stack contents.

Arithmetic Topics Affected by RPN Mode

This discussion of arithmetic using RPN replaces those parts of chapter 2 that are affected by RPN mode. These operations are affected by RPN mode:

!Two-number arithmetic (+, *, -, /, u).

!The percent function (%).

!The LAST X function (@L). See appendix E.

RPN mode does not affect the MATH menu, recalling and storing numbers, arithmetic done inside registers, scientific notation, numeric precision, or the range of numbers available on the calculator, all of which are covered in chapter 2.

Simple Arithmetic

Here are some examples of simple arithmetic. Notice that

!Eseparates numbers that you key in.

!The operator (+, -, etc.) completes the calculation.

!One-number functions (such as v) work the same in ALG and RPN modes.
