Memory calculation
Memory variable
The calculator has seven memory variables for repeated use -- A, B,
C, D, M, X, Y. You can store a real number in any of the seven
memory variables. See Example 5.
• [ 2nd ] [ STO ] + [ A ] ~ [ D ], [ M ], [ X ] ~ [ Y ] lets you store values
to variables.
• [ RCL ] + [ A ] ~ [ D ], [ M ], [ X ] ~ [ Y ] recalls the value of the
variable.
• [ 0 ] [ 2nd ] [ STO ] + [ A ] ~ [ D ], [ M ], [ X ] ~ [ Y ] clears the
content to a specified memory variable.
• [ ALPHA ] + " memory variable " lets you insert the applicable
variables in a calculation.
• [ 2nd ] [ CLR ] [ 2 ] [ = ] clears all variables.
Running memory
You should keep the following rules in mind when using running
memory. See Example 6.
• Press [ M+ ] to add a result to running memory and the " M "
indicator appears when a number is stored in the memory. Press
[ RCL ] [ M ] to recall the content of running memory.
• Recalling from running memory by pressing [ RCL ] [ M ] key does
not affect its contents .
• Running memory is not available when you are in statistics mode.
• The memory variable M and running memory utilize the same
memory area.
• In order to replace the content of the memory with the displayed
number, please press [ 2nd ] [ STO ] [ M ] key.
• To clear the content of running memory, you can press [ 0 ] [ 2nd ]
[ STO ] [ M ] in sequence.
(Note) : Besides pressing [ 2nd ] [ STO ] [ M ] key to store a value,
you can also assign values to memory variable M by
[ M+ ]. However, when [ 2nd ] [ STO ] [ M ] is used,
previous memory contents stored in variable M are
cleared and replaced with the newly assigned value.
When [ M+ ] is used, values is added to present sum in
memory.
