Do not even go there. The calculator is pretty basic and does not have memory to store instructions. If you want to take up programming ( a worthwhile endeavor) buy a graphing calculator such as a TI 89 itanium, a TI Voyage 200PLT, a TINspire, or a Casio Graphing calculator FX 9860 SD, ClassPad 330, or some top of the line HP calculators (HP 49G+, HP 50 G).

Ex. for 5^3, press 5, then "yx" (beneath "OFF" button), then the power (3), then press =... 5 --> yx --> 3 --> = --> 125. Hope this helps!

I had the same issue.

1. Open up the calculator.
2. Remove the battery.
3. Remove the two screws holding the display section down.
4. Carefully pry the button circuit board up and remove it.
5. Use an electrical cleaner and lint free cloth to wipe off the button circuit board.
6. Re-assemble and test.

For me, cleaning off the button circuit board restored all buttons to working order. When it is disassembled, and after cleaning, you could flip the board, display, etc. up and out of the case and test to see if it works as well.

Thanks! Genius!

I'm assuming the lack of a response means using the proper key did the trick.

Hello,
You add them normaly, not worrying about the display until the final result. Then you press [2nd][c/d] and it will converted.
Hope it helps

The following examples will demonstrate how to convert decimals into fractions using the TI-30Xa and TI-30Xa Solar. Please be aware that TI-30Xa Solar School Edition calculators do not have this functionality.

Example: Convert .25 to 1/4
- Input .25, press [2nd][<--] (says F<>D above it).

** F<>D means fraction to decimal, decimal to fraction.

Example: Convert 1.38 to 1_19/50

- Input 1.38, press [2nd][<--].

Example: Convert 9.75 to 9_3/4

- Input 9.75, press [2nd]{<--].

Hi,

Ex: calculate -log(15.32)

1. Calculate the log 15.32 [LOG] [=] result 1.185258765
   
2. Then press the change sign key (-) result -1.185258765

You can also try 15.32 [LOG] (-) [=]. Try to veriufy it on your calculator.

Here is a picture of the change sign
Hope it helps

2^-4

Press the STO key followed by one of the digits 1, 2, or 3 to store the number in the display to one of the three memories.

Why do you want to get out od Degree mode. If you are doing trigonometric calculations, the angle unit is pertinent. If you are not doing trigonometry, it is irrelevant. You say you can cycle through DEG, RAD, GRAD. That is the way to set the angle unit.However, there will always be an indicator on the screen (DEG, RAD, or GRAD).

Type in 4.73/(12.6*3.18EE(-)2 =

To clear any memory, store the value 0 in it.

How can you graph equations (functions) if you do not have a graphing calculator?
