If pressing CLEAR doesn't get rid of it, try resetting the calculator. Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries.

E shows on left of screen with 0 on right hand side. I can't get it to respond to any prompt.

sounds as if your calculator has registered a number to large to display. this can be done in either the normal calculating mode, or in the memory calculating mode. i will help with both scenarios.

for normal calculating mode:
try pressing the CE button and holding for about a half a second. the E should disappear and calculating function should resume.
if that doesn't work, try disconnecting power supply for a few seconds, then reestablishing power and hit CE

for memory calculating mode(there will be a M on the screen as well if this is the problem)
press either the CE or MC/MCE button for a half second. this should return normal function.
if that doesn't work, try the power reset as described above.

How do i plug in ((6^2+7.77^2+4^2)/(2x6x7.77)) in a TI-30XA calculator?

There should not be a problem: There are no complicated functions.
I suggest you do the calculation in steps
Step 1: Calculate the numerator 6^2+7.77^2+4^2=
The result will be stored in ANS memory, which you access by pressing the ANS key (either directly if marking is on the key, or by pressing 2nd followed by the key near which is the ANS marking).
Step 2: while the result is still displayed, press the division key, then a left parenthesis to enclose the denominator. Close the right parenthesis then press =

My TI-84 plus silver edition calculator crashed after my little sister held the "2nd" button and then pressed the down arrow key. The screen showed a 4, 3, 2, 1 countdown and then blanked out. I...

If your little sister did as you say, then the logical way to handle the problem is to revert the process.
  1. Press [2nd] button and release it.
  2. Press and HOLD the UpArrow.
  3. As you keep pressing, the top right of the screen will show a series a number, starting with 3 maybe, as you cannot see the 1 or 2, and the display will darken.
  4. Maintain pressure on, till the display is to your liking.

How to fix a none responsive button in hp 35s calculator

Resetting the Calculator
If the calculator doesn't respond to keystrokes or if it is otherwise behaving unusually, attempt to reset it. Resetting the calculator halts the current calculation and cancels program entry, digit entry, a running program, a SOLVE calculation, an ∫ FN calculation, a VIEW display, or an INPUT display. Stored data usually remain intact.

To reset the calculator, hold down the C key and press GTO . If you are unable to reset the calculator, try installing fresh batteries. If the calculator cannot be reset, or if it still fails to operate properly, you should attempt to clear memory using the special procedure described in the next section. If the calculator still does not respond to keystrokes, use a thin, pointed object to press the RESET hole.
The calculator can reset itself if it is dropped or if power is interrupted.


If the calculator fails to respond to keystrokes, and you are unable to restore operation by resetting it or changing the batteries, try the following MEMORY CLEAR procedure. These keystrokes clear all of memory, reset the calculator, and restore all format and modes to their original, default settings (shown below):
  1. Press and hold down the C key.
  2. Press and hold down the R/S key
  3. Press i (You will be holding three keys simultaneously)
  4. When you release all three keys, the display shows MEMORY CLEAR if the operation is successful.

You use the key combination [SHIFT][ANS] (DRG>).

If the default angle unit is degree
Type in the angle value in radian, say 1.2.
Press [SHIFT][ANS] (DRG>).
The screen displays 1: deg symbol, 2: a raised r for radian, and 3; a raised g (for grad).

1.2 [SHIFT][ANS] (DRG>) [2: raised r] .
The screen displays 1.2 with a raised r to the right of the 2.
Press [=].

The answer is 68.75493542
