It is one of the more popular graphing calculators for students (especially those in middle school or higher). It includes many different features and functions, including function graphing, polar/parametric/sequential modes, statistics, trigonometric, and algebraic functions, and many functions present on normal scientific calculators. Although it does not include as many calculus functions, applications (for the TI-83 Plus -- see below) and/or programs can be downloaded from various websites that allow for them.

The TI-83 was replaced by TI with the TI-83 Plus calculator in 1999, which included Flash ROM, enabling the device's operating system to be updated if needed, or for large new Flash Applications to be stored , accesssible through a new (Apps) key. In 2001 the ante was raised with the TI-83 Plus Silver Edition, which featured approximately nine times the available Flash ROM, and twice the processing speed (12 MHz) of a standard TI-83 Plus, all in a translucent, iridescent grey case.

The original 83 is itself an upgraded version of the TI-82.
