Using Memory Functions
Answer Memory (Ans)
Whenever you press after inputting values or an expression, the calculated result automatically updates Answer Memory contents by storing the result.
fx-82MS/fx-85MS/fx-300MS/fx-350MS: 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).
fx-220 PLUS: In addition to , Answer Memory contents are also updated with result whenever you press (%), , (M-), or (Min).
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.
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
