Memory Calculations
k Independent Memory
• Values can be input directly into memory, added to
memor y, or subtracted from memory. Independent
memory is convenient for calculating cumulative totals.
• Independent memory uses the same memory area as
variable M.
• To clear independent memory (M), input

k 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
all nine variables:
A
C
=
.
• Use the following operation to delete data assigned to a
particular variable:
0
j
1
. This operation deletes
the data assigned to variable A.
