The TI-82 is a graphing calculator made by Texas Instruments. The TI-82 was designed in 1993 as an upgraded version of and replacement for the TI-81. It was the direct predecessor of the TI-83. It shares with the TI-85 a 6 MHz Zilog Z80 microprocessor. Like the TI-81, the TI-82 features a 96×64 pixel display, and the core feature set of the TI-81 with many new features.

The TI-81 was the first graphing calculator made by Texas Instruments. It was designed in 1990 for use in algebra and pre-calculus courses. Since its release, it has been superseded by a series of newer calculators; most of these are functionally similar to the TI-81, with the exception of the TI-Nspire series.

The TI-80 is a graphing calculator introduced by Texas Instruments in 1995 to be used at a middle school level (grades 6 to 8). It offered advanced capabilities that had previously only been available in high-end scientific calculators to students learning pre-algebra and algebra, and was designed to be affordable for schools.
