The TI-30XIIS is Texas Instruments' two-line scientific calculator for middle school, high school and college math and science. It handles fractions, statistics, trigonometry, logarithms and powers, and shows an entry on one line and its result on the next, so you can check what you typed. It runs on a battery with solar backup, so it keeps working in dim rooms and in exams. It is simpler and cheaper-feeling than graphing models like the TI-84, but it covers most coursework that does not require graphing, and it is one of the most widely required calculators on school supply lists.

Owners and reviewers treat the TI-30XIIS as a dependable, no-frills school calculator. They like the two-line display, the fraction handling and the solar backup, and many say it survived years of daily use. Complaints center on the small, unlit screen and the learning curve for its menus.
