Using Memory Functions

Answer Memory (Ans)/Previous Answer Memory
(PreAns)
The last calculation result obtained is stored in Ans (answer) memory. The
calculation result obtained prior to the last one is stored in PreAns
(previous answer) memory. Displaying the result of a new calculation will
move current Ans memory contents to PreAns memory and store the new
calculation results in Ans memory. PreAns memory can be used only in
the COMP Mode. PreAns memory contents are cleared whenever the
calculator enters another mode from the COMP Mode.
