CASIO

Whenever you press after inputting values or an expression, the calculated result automatically updates Answer Memory contents by storing the result.

In addition to , Answer Memory contents are also updated with result whenever you press (%), , (M-), or (STO) followed by a letter (A through F, or M, X, or Y).

You can recall Answer Memory contents by pressing .

Answer Memory can store up to 15 digits for the mantissa and two digits for the exponent.

Answer Memory contents are not updated if the operation performed by any of the above key operations results in an error.

Consecutive Calculations

You can use the calculation result that is currently on the display (and also stored in Answer Memory) as the first value of your next calculation. Note that pressing an operator key while a result is displayed causes the displayed value to change to Ans, indicating it is the value that is currently stored in Answer Memory.

The result of a calculation can also be used with a subsequent Type A function (x2, x3, x-1, x!, DRG), +, -, xy, x√ , ×, ÷, nPr and nCr.

Example 1: To divide the result of 3 × 4 by 30

• 34
• 12.

• (Continuing)　30
• 

Example 2: To perform the calculations shown below:

• 123456
• 579.

• (Continuing)　789
• 210.

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.

Example:

To assign the result of 3 + 5 to variable A

• 35(STO)(A)
• 8.

To multiply the contents of variable A by 10

• (Continuing)　(A)10
• 80.

To recall the contents of variable A

• (Continuing)　(A)
• 8.

To clear the contents of variable A

• 0(STO)(A)
• 0.

You can add calculation results to or subtract results from independent memory.

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

Example 1:

To clear the contents of M

• 0(STO)(M)
• 0.

To add the result of 10 × 5 to M

• (Continuing)　105
• 50.

To subtract the result of 10 + 5 from M

• (Continuing)　105(M-)
• 15.

To recall the contents of M

• (Continuing)　(M)
• 35.

Example 2:

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

• 239(STO)(M)
• 32.

• 536
• 47.

• 452(M-)
• 90.

• 993
• 33.

• (M)
• 22.

Independent memory and variable contents are retained even if you press , or turn off the calculator.

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