The TI-30XIIS is Texas Instruments' two-line scientific calculator for middle school through college math and science. It shows an entry on one line and the result on the other, so you can check what you typed before you press enter. It runs on a CR2025 battery with solar backup, so it keeps working in dim rooms and exams. It is simpler and cheaper-feeling than graphing models like the TI-84, but it covers the fractions, statistics and trig most courses need.
