All other operations－including the Solver－work the same in RPN and ALG modes. (The Solver uses algebraic logic only.)
For more information about how RPN works, see appendix E, “RPN: The Stack.” For RPN keystrokes of selected examples from chapter 14, see appendix F, “RPN: Selected Examples.” Continue reading in chapter 2 to learn about the other functionality of your calculator.
Watch for this symbol in the margin earlier in the manual. v It identifies keystrokes that are shown in ALG mode and must be performed differently in RPN mode. Appendixes D, E, and F explain how to use your calculator in RPN mode.
The mode affects only arithmetic calculations－all other operations, including the Solver, work the same in RPN and ALG modes.
Setting RPN Mode
The calculator operates in either RPN (Reverse Polish Notation) or ALG (Algebraic) mode. This mode determines the operating logic used for arithmetic calculations.
To select RPN mode: Press @> .
The calculator responds by displaying . This mode remains until you change it. The display shows the X register from the stack.
To select ALG mode: Press @> . The calculator displays
