Calculations with STO and RCL
The store (
s
) and recall (
R
) operations work identically in ALG
and RPN modes (see “Storing and Recalling Numbers” and “Doing
Arithmetic Inside Registers and Variables” in chapter 2). The keystrokes
are the same for simple storing and recalling and for doing arithmetic
inside registers and variables.
When doing arithmetic in the display with values from storage registers
and variables, remember to use RPN. Compare these keystrokes in RPN
and ALG modes:

Chain Calculations－No Parentheses!
The speed and simplicity of calculating using RPN are apparent during
chain calculations
－longer calculations with more than one operation.
The RPN memory stack (refer to appendix E) stores intermediate results
until you need them, then inserts them into the calculation.
