Some TI83's can be set up differently, so it is highly recommendable to read the user guide for the TI83 in question. The user would need to go into the VarStat option and enter all the appropriate fields to have the calculator bring in the appropriate variables and totals.
Press mode, highlight SCI and press ENTER. The calculator is now in scientific notation mode. Press 2nd quit. Now, if you do a calculation such as 1234 x 5678, the answer will be in scientific notation. (In this case, 7.006652ᴇ6, which stands for 7.006652 x 106)
Press MODE and select NORMAL at the top. (You may notice that SCI was selected for scientific notation.)
There are online graphing calculators. However, as of writing, there is no emulated TI83 that runs within your browser. On the other hand, if you have a Ti83, it is possible to copy its ROM to run an emulated TI83 on your desktop via one of many emulators.
Go to the y= button, and type in your equation by the y1 (if there's 2 equations, press enter and type the 2nd one in by the y2). Then press graph.
Short answer; you can't. But you can purchase (or borrow) a TI84 calculator and use the TI83's transfer cable to transfer data from the 83 to the 84 to your mac computer (the TI84 comes with a USB transfer cable).

The TI-83 calculator uses 4 AAA batteries.
You cannot. A calculator is programmed. It is made to calculate correctly.
It will depend on the class. Nothing is impossible without the TI83, but some classes might require it so you can graph and write programs to go along with the math curriculum.

No. I believe TI83+ and TI84 do use an operating system.
Yes. The TI83 has several applications that can be downloaded onto the TI83, mainly those made by Texas Instruments. Also, you can write your own software.

change the batteries! There are two types of batteries in the ti83 calculator -- ordenary AAA batteries and one flat one. Buy new ones and change ... or else be more specific when asking. Yenn, DK
