– Independent memory. Values can be input
directly into memory, added to memory, or
subtracted from memory. Independent memory
is convenient for calculation cumulative totals.
Independent memory uses the same memory
area als variable M. To clear independent memory

– Variables. There are nine variables (A through
F, M, X and Y), which can be used to store data,
constants, results and other values. Use the
following operation to delete data assigned to
a particular variable:
(A). This operation deletes the data assigned to
variable A. Perform the following key operation
when you want to clear the values assigned to all
of the variables:
(CLR)
