Try entering on the same command line your calculation followed by the ToFrac command. That should work. Here is a screen capture from a TI83Plus in complex mode (a+ib).

When ever i turn on my ti-84, it says waiting..... PLease install operating system now.


Hi biancaaii,

You need to re-install the Ti 84 Plus OS, ASAP!!! You can fix the problem by installing the newest Ti 84 Plus 2.55v. MP OS. operating system.

If you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the IO link ports and, they can send you a copy of their OS while you receive it on your Ti 84 Plus. Hopefully your friend will have Ti84 Plus 2.55v. MP OS on their calculator or, it might not work.

If you can't find a calculator to connect to you can connect your Ti 84 Plus to a computer that has Ti Connect software on it. If you need to connect your Ti 84 Plus to a computer make sure the Ti Connect software is operating properly. You do not want any hang-ups while installing the Ti 84 Plus OS. Be careful, even a power failure during the process of installing the OS will destory your calculator.

Procedure 1 to installing the latest Ti84 Plus 2.55v. MP OS

1). You can get the latest copy of Ti84 Plus 2.55v. MP OS and, guidebook by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 84 Plus 2.55v. MP OS!" Once your at the Ti site click the Download Item, "Ti84 Plus family operating system". Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti84 Plus family operating system will download to you.

Next, click "SAVE" and then a window to a folder will pop up. It is probably a window to a folder that you download too. If so, you may want to change it and, save to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 84 Plus guidebook too, if needed.

Link your computer and, Ti 84 Plus calculator with the USB cable or, Direct Black Link cable that came with the Ti 84 Plus calculator. Next, drag the Ti 84 Plus 2.55v MP OS that you saved earlier in "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Click, "Continue" when the "Erase Warning" pops up and, the new Ti 84 Plus 2.55v MP OS will begin to install.

Next, the Ti Device window should pop up and, highlight the port when it finds what your Ti 84 Plus is using, USB1 cable or, Direct Black COM1.

When the Ti Device Explorer finds and, highlights your calculator's information click, "Select." Then click, "Yes" when the next window shows up with your calculator's information and, the OS will continue to download. Upon completion the newest Ti 84 Plus 2.55v. MP OS will be installed.

If you run into any trouble with software or, drivers just comment to what failed at this posting and, I'll be glad to help you.

How do you use a plus or minus sign on a TI-84


Hi,
You cannot use the ± in the definition of a function. If you need to consider two alternatives, you have draw each function separately, one function as Y1 and the other as Y2. I just checked the catalog of commands, and there is no ±.

Hope it helps.
Thanks for using FixYa

The memory button on my TI-84 Plus will not function


If you connect it to the computer using ti connect device explorer you can try to do everything from there. Manage your memory. If you saying the plus sign is broke too, because it is the memory key too. I wonder if you "+">a would work. Just 2nd recall "a" when you need the plus sign. You can store it in any variable you want. Setting up systems to operate your calculator's memory management can be done on command or Entry Line. Much easier with Ti connect. You don't really need the plus sign or memory key to run very good memory management programs. Just remember to download from this site my ti 84 plus silver manual on how unarchive and run programs. I really don't recommend taking the calculator apart, they usually end up broke at that point.

From TI FAQs:

What troubleshooting can I try if the TI graphing calculator will not turn on?

For the TI-83 Plus Family, TI-84 Plus Family:

  1. Try a new set of AAA batteries.
  2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
  3. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.
  4. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
