In RPN mode, you enter:

3
In other words, in RPN mode 52 and 3 are
entered onto the stack before the conunand
is entered; 52 must be on level 2 and 3 on
level 1 before the command is executed.
Strictly speaking, the last (or only) argument does not need to be on the
stack before you execute a command in RPN mode. You can execute a
command with the last (or only) argument still on the command line.
Therefore, the second (BW) in the example immediately above can be
omitted. However, any argument still on the command line when a
command is executed will not be displayed on the stack if you undo the
command (which you can do by pressing R(DND0)). Therefore, if you think
you may need to imdo a command and be able to see all the arguments,
you should put all the arguments onto the stack before executing the
command.
Example stack calculations
Using a one-argument command
1. If the argument is not already on level 1 of the stack, enter the
argument onto the conunand line (and, optionally, onto the stack). If
the argument is already on level 1 of the stack, go straight to step 2.
2. Execute the command.
Example: To calculate
1
sin 30
1. Enter 30 and press
2. Press (sin).
The result of sin 30 is now on level 1 of the stack. This result can be
used as the argument of a further command without the result needing
to be manually entered.
3. Press (3-
Note that if you get a symbolic answer when you wanted a niunerical
answer, press 0@yM). The symbolic answer is evaluated.
