Using Memory Functions

Answer Memory (Ans)
The last calculation result obtained is stored in Ans (answer) memory.
To divide the result of 14 × 13 by 7
123 + 456 = 579
789 − 579 = 210
Variables (A, B, C, D, E, F, M, x, y)
You can assign values to variables and use the variables in calculations.
To assign the result of 3 + 5 to variable A
To multiply the contents of variable A by 10
To recall the contents of variable A
(Continuing) (RECALL)*
To clear the contents of variable A
*1 Input a variable as shown here: press  and then press the key that
corresponds to the desired variable name. To input x as the variable
name, you can press (x) or .
*2 Pressing (RECALL) displays a screen that shows the values
currently assigned to variables A, B, C, D, E, F, M, x, and y. On this
screen, values are always displayed using the "Norm 1" Number
Format. To close the screen without recalling a variable value, press
.
Independent Memory (M)
You can add calculation results to or subtract results from independent
memory. The "M" appears on the display when there is any value other than
zero stored in independent memory.
To clear the contents of M
To add the result of 10 × 5 to M
To subtract the result of 10 + 5 from M
To recall the contents of M
Note: Variable M is used for independent memory. You also can call M and
use it in a calculation you are inputting.
