RPN and ALG Keys

The calculator can be set to perform arithmetic operations in either RPN (Reverse

Polish Notation) or ALG (Algebraic) mode.

In Reverse Polish Notation (RPN) mode, the intermediate results of calculations are

stored automatically; hence, you do not have to use parentheses.

In algebraic (ALG) mode, you perform addition, subtraction, multiplication, and

division in the traditional way.

To select RPN mode:

Press

to set the calculator to RPN mode. When the calculator is in RPN

mode, the RPN annunciator is on.

To select ALG mode:

Press

to set the calculator to ALG mode. When the calculator is in ALG

mode, the ALG annunciator is on.

Example:

Suppose you want to calculate 1 + 2 = 3.

In RPN mode, you enter the first number, press the

key, enter the second

number, and finally press the arithmetic operator key:

In ALG mode, you enter the first number, press

, enter the second number, and

finally press the

key.

RPN mode ALG mode

In ALG mode, the results and the calculations are displayed. In RPN mode, only

the results are displayed, not the calculations.

Note

You can choose either ALG (Algebraic) or RPN (Reverse Polish

Notation) mode for your calculations. Throu

hout the manual, the

“

“ in the mar

in indicates that the examples or keystrokes in

RPN mode must be performed differently in ALG mode. Appendix

C explains how to use your calculator in ALG mode.
