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.)
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.
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.
No, it really depends on the college. Some colleges don't allow any calculators for their math classes. Everything that can be done on a TI83 can be done with the human brain, so some professors make tests with easier computations so that you don't have to use a TI83
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.
Press "ALPHA", then press "."
The TI-83 calculator uses 4 AAA batteries.
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.
You cannot. A calculator is programmed. It is made to calculate correctly.

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).
