Capabilities: This model is capable of Trig, statistics, multifunction graphing and there are a ton of online programs that can be downloaded to assist in higher level math. In addition literally hundreds of games have been made specifically for the TI-83 model. Functions, Parametric equations, Polar equations, and Sequences can all be graphed using this model. You can also create new executable programs either on the calculator itself or on a computer. The calculator comes with a usb transfer cord so anything created or found via the computer can be easily transferred to the device.Layout: Everything in the TI-83 starts at the home screen, which is blank ready for input of instructions. The 83 does lack the multiple different destinations that the TI-89 offers such as finance, but these applications can be entered and accessed following the applications button. The second main screen that can be accessed is the graph screen. It is pretty straightforward, but in order to change the type of equation being graphed you must hit mode and change the positions from function to whatever else you want. Luckily the calculator also comes with a manual so all these intricate details can be processed without too much effort. The layout is very straightforward.
Deficiencies: The only main deficiency with this calculator is it's inability to integrate or differentiate. When the object of the calculation is no longer simple learning of these definitions, it can be a hassle to have to compute these calculations in higher level logic based courses.
Overall Impression: If you are going into Algebra 1 or beyond I would suggest you buy this calculator. If you are currently about to enter calculus 3 or Differential Equations it might be more beneficial to buy the TI-89. I used the TI-83 throughout all of Calculus, Differential Equations, and Matrix Theory. It is approved for the SAT. Make sure the calculator is approved by your class or school to use, although it is approved almost everywhere.
