SOURCE: all of my apps, gone !
Please do not dislike your math teacher, for your own sake: You will not learn much from someone whom you dislike. Now Relax.
All the applications that were preloaded in your calculator are available to download freely from http://education.ti.com Use the tab Download--> Apps and software. Then select software for the TI83/TI84 Family. While you are at the site download the TI Connect, if yoy do not have it already. The link follows.
http://education.ti.com/educationportal/sites/US/productDetail/us_ti_connect.html You can also download the latest OS there.
Install TI connect on your computer and run it to open the main Window.Then connect you calculator to a USB port and, in the TIConnect main window Click the TIDeviceInfo icon. Software will try to retrieve the info. If it does your calculator is ready to communicate with the computer.
If it tells you Device Not found , Click communication settings in same pop up window where it said Not found, and Select Device, Select Cable (USB or TIsilver cable), Select Port (USB1) and Click OK..
If you are lucky and it works, you can reinstall the OS, which can be downloaded from education.ti.com. You drag and drop the OS on the TIconnect main window. Calculator must of couse be connected to computer. To install an application already downloaded to you computer, drag it to the main window of TI Connect and drop it. Keep installing, the appilcations you want.
If you have problem with TIconnect, use the calc-to-calc cable to transfer the Apps on a working calculator. Yous should be on Receive mode [2nd][Link] --->>Receive. (When both calculators are ready hit enter.) The other calculator, you guessed exactly right, must be on Send [2nd][Link][SEND][C:Apps]. A list of Apps appears. Scroll down the list. If you want to transmit un app you press [ENTER] when the arrow reaches its line. Once an app is selected , a small square appears on the left. After the selection, Hit transmit. I suggest you transfer Apps, one after the other. Avoid selecting them all and send them all at one go.
Hope it helps

Testimonial: "i'll try not to hold a grudge against my math teacher lol THANK YOU SO MUCH!"
the 89 is in my opinion not need/ approriate for a 10th grade algebra class, or worth the extra money.
for example the 84 wont output variables it must output a number
so your son may be doing factoring, if he inserts (x^2+2x+1) the 89 will allow him to enter it and factor it as (x+1)(x+1) or (x+1)^2 the 84 will not.
the 84 will do pleanty as far as graphing, finding zeros,plotting, calculations, and should get him any answer that he seeks so long that he knows how to use the 84. It just wont give him the intermediate steps the the 89 is able to give.
hope this helps
