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.
