Memory

Memory Calculations

The memory function is convenient for calculating cumulative totals.

[M+]	Adds displayed value to memory.
[MR]	Recalls the value stored in memory.
[SHIFT] [MC]	Clears memory.
[SHIFT] [M-]	Subtracts the displayed value from memory.
[SHIFT] [X-M]	Swaps the displayed value with the value currently in memory.

Constant Memory Calculations

A pair of constant memories let you store operators and values. Once stored, a value and operator can be recalled with the touch of a key as necessary.

•Arithmetic operators (+, -, x, ⎟), power, and root operations can be stored in constant memory.

•An error will occur if you try to store only an operator or only a value.

•You can store data in constant memory immediately after pressing the [AC] key.

•Storing data to a memory that already contains data replaces the old data with the new.

[SHIFT] [SET1]	Stores data into constant memory F1.
[SHIFT] [SET2]	Stores data into constant memory F2.
[F1]	Recalls data from constant memory F1.
[F2]	Recalls data from constant memory F2.
[AC] [SHIFT] [SET1]	Clears constant memory F1.
[AC] [SHIFT] [SET2]	Clears constant memory F2.
[AC] [F1]	Displays the contents of constant memory F1.
[AC] [F2]	Displays the contents of constant memory F2.

Examples:

To store x 123 in constant memory F1: [AC] [x] [123] [SHIFT] [SET1]

To use constant memory (multiply by 123): [AC] [2] [F1]
