The TI-30XIIS is Texas Instruments' mid-range scientific calculator for middle school through college math and science. It runs on two AA batteries with solar backup, so it keeps working in dim rooms and rarely needs a battery change. It handles fractions, statistics, logarithms, trigonometry and a two-line display that shows the entry and the result together. It sits above the basic TI-30Xa and below the graphing TI-84, and teachers and students widely treat it as a dependable, no-frills choice for standardized tests.
