Using Memory Functions

Answer Memory (Ans)

The last calculation result obtained is stored in Ans (answer) memory.


Note

Ans Memory contents are updated whenever you execute a calculation using any one of the following keys: , (≈), , (M−), (RECALL), .

Ans Memory contents are not change if an error occurs during the current calculation.


Using Ans Memory to Perform a Series of Calculations

Example: To divide the result of 3 × 4 by 30

  • 34
  • (Continuing) 30
  • Pressing automatically inputs “Ans” command.

With the above procedure, you need to perform the second calculation immediately after the first one. If you need to recall Ans Memory contents after pressing , press the key.


Inputting Ans Memory Contents into an Expression

Example: To perform the calculations shown below:

  • 123456
  • (Continuing) 789

Variables (A, B, C, D, E, F, M, x, y)

Your calculator has nine preset variables named A, B, C, D, E, F, M, x, and y.
You can assign values to variables and use the variables in calculations.


You can assign a specific value or a calculation result to a variable.

Example: To assign the result of 3 + 5 to variable A.

  • 35(A)

Example: To assign the result of 4 × 6 to variable x.

  • 46(x)

Use the following procedure when you want to check the contents of a variable.

Example: To recall the contents of variable A

  • (Continuing) (RECALL)*1
  • (A)

*1 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 .


The following shows how you can include variables inside of an expression.

Example: To multiply the contents of variable A by the contents of variable B

  • (Continuing) 12(B)
    (A)(B)*2

*2 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).


Example:  9×6+3　5×8　 = 1.425

  • 963(B)
  • 58(C)
  • (B)(C)(≈)

Clearing the Contents of a Specific Variable

Press 0 and then press the key for the name of the variable whose contents you want to clear.

Example: To clear the contents of variable A

  • 0(A)

Independent Memory (M)

You can add calculation results to or subtract results from independent memory. The “M” appears on the display when independent memory contains a value.

The following is a summary of the different operations you can perform using independent memory.

To do this: Perform this key operation:
Add the displayed value or result of the expression to independent memory
Subtract the displayed value or result of the expression from independent memory (M−)
Recall current independent memory contents (RECALL)(M)

Variable M is used for independent memory.

You can also insert the M variable into a calculation, which tells the calculator to use the current independent memory contents at that location. The following is the key operation for inserting the M variable.
(M)

The “M” indicator appears on the display when there is any value other than zero stored in independent memory.


Calculation Examples Using Independent Memory

If the “M” indicator is on the display, perform the procedure under “Clearing Independent Memory” before performing this example.

Example:  23 + 9 = 32
53 - 6 = 47
-) 45 × 2 = 90
99 ÷ 3 = 33
(Total)　 22

  • 239
  • 536
  • 452(M−)
  • 993
  • (RECALL)(M)

Clearing Independent Memory

Press 0(M). This clears independent memory and causes the “M” indicator to disappear from the display.

  • 0(M)

Clearing the Contents of All Memories

Ans memory, independent memory, and variable contents are retained even if you press , change the calculation mode, or turn off the calculator.


Perform the procedure below when you want to clear the contents of all memories.

(RESET)(Memory)(Yes)

To cancel the clear operation without doing anything, press (Cancel) instead of .
