Using Answer Memory (Ans)
The result of any new calculation you perform on the calculator is stored automatically in
Answer Memory (Ans).
A Automatic Insertion of Ans in Consecutive Calculations
If you start a new calculation while the result of a previous calculation is still on the display,
the calculator will insert Ans into the applicable location of the new calculation automatically.
Example 1: To divide the result of 3 × 4 by 30
b
3*4E
(Next) /30E
Pressing
/ inputs Ans automatically.
Example 2: To determine the square root of the result of 3
2
+ 4
2
b
3x+4xE
!E
Note
• As in the above examples, the calculator automatically inserts Ans as the argument of
any calculation operator or scientifi c function you input while a calculation result is on the
display.
• In the case of a function with a parenthetical argument (page 15), Ans automatically
becomes the argument only in the case that you input the function alone and then
press
E. Note, however, that with natural display Ans may not become the argument
automatically when using a function with a parenthetical argument.
• Basically, Ans is inserted automatically only when the result of the previous calculation is
still on the display, immediately after you executed the calculation that produced it. If you
want to insert Ans after clearing the display by pressing
o, press 1-(Ans).
