When I first type into my calculator it writes the numbers upside down on the bottom of the screen first. Then as I continue to type in numbers it will still write them upside down but will continue at the top. I have tried everything that I have read on this website. I don't know what else to do and of course I really need my calculator because I have stats exam tomorrow. Please help me.

Thats because the OS is corrupt. Follow the manual and reload the OS, try the 2.43 OS
SOURCE: Screen is upside down as I type
Was it a prank ?
I have read that to invert the LCD-screen you just flip the polarisation-plate (the plastic film that sits over the LCD display) 180º, that is , upside down.
SOURCE: Numbers are upside down. How do I turn them around?
Hello,
Frankly, I would love to see that. More seriously, now, if problem is software related you may be able to recover you calculator.
Use the link below to install TIConnect software
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. It will try retrieve the info.If it does your calculator is fine. Fill the screen with letters, symbols, numbers, and use TI connect ScreenCapture icon and compare the image with the actual screen. This may serve as a diagnostic tool in case you have to take calculator for repairs.
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, Select Port and try OK. If you are lucky and it works, you should 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.
If you have problem with TIconnect, use the calc-to-calc cable to transfer the OS of 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][G:SendOS]. (When both calculators are ready hit [ENTER])
If all that does not work, then it may be time to head for a place of worship to pray for its resurection, or look for a repair shop.
Hope it helps

Hello,
Press [CLEAR] to erase the screen. If that does not work reset the RAM
Press [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]. Then press [CLEAR].
If these steps fail, you should read the article.
Hope it helps.

Step 3: Write down 75 with the decimal place 2 spaces from the right (because 100 has 2 zeros);

Step 3: Write down 1875 with the decimal place 4 spaces from the right (because 10,000 has 4 zeros);
