Answer Memory (Ans)/Previous Answer Memory
(PreAns)
The last calculation result obtained is stored "' Ans ':answer) memory, The
calculation result obtained prior to the last one is sto<ed "' PreAns (previous
answer) memory. Displaying the result of a new calculation willmove 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.
For T,-, = T,.\ + T, (Fibonacci sequence), determine the sequence
from T, to T,. Note however, that T, = 1 and T, = 1.

Variables
(A,B,C,D,E,F,X,Y)
Your calculator has eight preset variables named A, B, C. D, E, F, X, and Y. You
can assign values to variables and also use the variables in calculations.

You can add calculation results to or subtract results from independent
memory.The "M" appears on the displaywhenthere isany valueother

Clearing the Contents of All Memories
Ans
memory, independent memory, and
variablecontentsare retainedeven
if you press
gg, change the calculation
mode, or turn off the calculator.
PreAns memory contents are retained even if you press
gg
and turn off the
calculator without exiting the COMP Mode. Perform the following procedure
when you want to clear the contents of alt memories.
