If you don't see it on the screen thats because it's changing the number into a letter (1+alpha,alpha=Z).
If the key is not working it needs a new key pad.

What I do is not reccomended. Remove the battery and the power cable. Then replace the battery and power cable.

Key working alpha


The alpha key activates the alphabet keyboard and a few extra symbols. To access the MATH menu and the ToFrac command, press the key below the ALPHA key. The key is marked with MATH.
On the TI84PLUS with the newer operating systems (version2.5x), the APLHA key opens up a few functionalities. That is not available on the TI 83Plus.

Alpha keyboard not working


if usb keyboard and local keyboard aren't working i'd check to see if you have a fuction key pressed that disables you from using the keyboard, try restarting, if it solves the issue it was a FN key if not, problems deeper and you may want to look at hardware diagnostics

Alpha key not recognized when pushed


When the ALPHA key is pushed the cursor shows an A. Press one of the keys that has the same color as the ALPHA key (A,B,C,...X,Y,Z).
If you have the MathPrint OS, the ALPHA F1/F2/F3/F4 sequence activates shortcuts to newe features (fractions, logab, sums etc..)

How do you solve log problems on your calculator


I have no idea what type of log problems you want to solve. It does help to know what you have in mind. To type in the log function log(, you have two ways:
1. Use the keyboard to type it in on the command line APLHA L, ALPHA o, ALPHA g followed by opening parenthesis. Or if you can LOCK the alpha keyboard, lock it and press the keys corresponding to the letters l, o, and g.
2. Press [Diamond key] [7]
The last trick works on the TI92 and TI Voyage 200 PLT which have a full fledged keyboard. Try it anyway, if that does not work you can still use the ALPHA keyboard.

Many keys in this calculator serves one than one function which can be access through by pressing either "2nd"(Blue Key) or "ALPHA"(GREEN KEY). Such extra functions are noted on keys in Green or Blue color. These additional functions are accessed by first pressing corresponding color key and desired function Key.

For example:
pressing UP and DOWN keys navigates the screen up and down
if we press ALPHA key and then UP/DOWN key, it will scroll screen UP/DOWN by a page. Also you can use this combination for copy functions.

Casio fx-300es. How do you enter a variable? what button do you press to represent x in x+7=14 or any other problem with a variable. Everyone has a ti 84 and they have a button for x.


You have a way to enter the Variables A, B,C,D, Y and X.
Use the ALPHA key
For A use ALPHA change sign key (-), below the Fraction Template.
For B use ALPHA (degree ' ")
For C use ALPHA (HYP)
For D use ALPHA (SIN)
For X use ALPHA right )
For Y use , ALPHA (S-D) key
For =, use ALPHA and the key below the SHIFT key. May be marked CALC. The = is in the same color as the ALPHA on calculator. It should be to the upper right side of a key.

(I have an FX-991ES that is compatible with the FX-300ES, but since I do not have a picture of the FX-300ES calculator I cannot be more specific than I have been, lest I mislead you.)
