Memory Calculations

There are different types of memory available:

Answer Memory, Consecutive Calculations, Independent Memory, and Variables.

Answer Memory

Whenever you press [=] after inputting values or an expression, the calculated result automatically updates the Answer Memory contents by storing the result. You can recall it by pressing [ANS].

Consecutive Calculations

You can use the calculation result that is currently on display (and also stored in Answer Memory) as the first value of your next calculation.

Independent Memory

Independent Memory uses the memory area in variable M and is convenient for calculating cumulative totals.

To add a value to M, press [M+].

To subtract a value from M, press [SHIFT] [M-]. To recall the value of M, press [RCL] [M].

Variables

There are 9 variables available (including M) to store data (A through F, M, X, and Y). To add a value to memory letter A, enter the value and press [SHIFT] [STO] [A].

To recall the value of A, press [RCL] [A]. Note: Do NOT use the ALPHA key.

Clearing Memory

To clear independent memory, press [0] [SHIFT] [STO] [M] (this stores 0 in M).

To delete data assigned to a specific variable, press [0] [SHIFT] [STO] <> (enter the letter you want to clear, without pressing the ALPHA key).

To clear the values assigned to all of the variables, press [SHIFT] [CLR] [1] [=].
