It depends on what you want to use it for. If you are looking for something that just does basic mathematical calculations, any electronics store has any number of choices.

If you are looking for something to help with higher math (calculus) TI's TI-83 and 84are pretty much the standard.

Ti 84 plus can't transfer 8C010000


Transferring data and programs to the calculator requires a lot of energy that almost dead batteries cannot provide. Change batteries and try the transfer again using TI Connect. To transfer from a similar calculator the receiving one must be in RCV (receive mode).

Can you transfer ti83 os to ti 84?


The TI83Plus has the capability to transfer its OS to another handheld device. It is possible that the TI84Plus hardware will accept it. But why downgrade?. Why not resinstall the OS? The latest version 2.55MP is available on the TI website.
You say emphatically that you tried everything and maybe so, but I will ask you: Have tried to connect the calculator to a computer and explored its content with TI connect. You may retrieve some information about its status.
The TI connect software will allow you to transfer a version of the OS even if the calculator appears to refuse to turn ON (screen contrast problem.) If it cannot it will let you know.

Try again.

Our t84 won't hold any battery life. we have changed both the lithium and the tripl a's and you can only use the calculator one and then its out of battery......what is going on?


Possibility: Some third-Party programs (games essentially) are installed on the calculator. They may be ill-designed and circumvent/turn OFF the Power saving features of the calcuator.Also, Texas Instruments recommends to use alkaline (non-rechargeable) batteries only.

When i turn my calculator on it says "RAM cleared". It is then very slow . . . what is wrong and how can I fix it?


Hi yeager anna,

Since the calculator operates slowly even after the RAM has been cleared, I'd say, "Your OS must be corrupt." You need to re-install the Ti 84 Plus OS, ASAP!!! You can fix this problem by installing the newest Ti 84 Plus 2.55v. MP OS, operating system. Use fresh batteries when installing the new OS. If you need additional instructions your welcome to read my Ti 84 Plus solutions. I pretty much tell how you can install the new OS with another Ti 84 Plus calculator or, connecting the computer to the calculator to install the new OS. You can view my solution to install OS by clicking, "Ti 84 Plus OS installation." Just stroll down to oneplusgh's solution at that posting and, I cover a lot of topics you may need advice on to install the new OS.

If you need instructions to downloading and installing TI Connect on a XP or, Mac computer click, "TI Connect on a XP or Mac computer." I realize this posting was for a later OS but, this link will take you to the latest TI Connect software and, newest OS too. Once you get the TI Connect software installed come back to this posting and, follow the instructions above at "Ti 84 Plus OS installation."

If you need instructions to downloading and installing TI Connect on a Windows 7 computer click, "TI Connect on a Windows 7 computer." Just follow Procedure 3. You can also get instructions at this link on how to install the Ti driver to link computer and calculator. I realize this link instructions were for a Ti 89 calculator but, they will work for a Ti 84 Plus too. Once you get the TI Connect software installed come back to this posting and, follow the instructions above at "Ti 84 Plus OS installation."

My instructions is geared to save you a lot of hardship. No matter if your having to install Ti Connect or, the newest OS for your calculator. I do not use TI OSDownloader because, TI OSDownloader might not give you the newest OS for your calculator. My instructions will. If you have any questions just post a comment and, I'll respond quickly.

Comma key on TI-84 Plus Siver Edition calculator.


The comma key on the TI 84 SE is above the 7 key, and it is just left of (, right of x squared, and below SIN. thats where the "," key is. If you're asking something else, please clearify. My understanding is that you don't know where the comma key is.

Can you Factor on a TI-84? IF not, does the TI-89?


Well, to answer part of your question, yes... the TI-89 does factor like this. it is inputted like this:

factor(6*x^2+11*x+4,x)

Check the catalog in the TI-84 (which is 2nd-zero) and look under F for factor()
