Texas Instruments TI-30Xa 10-digit Scientific Calculator - Grey

The Texas Instruments TI-30Xa is a pocket-sized calculator for school mathematics and basic science courses. It features a 10-digit, single-line LCD. The model handles scientific and trigonometric functions, fractions, and one-variable statistics. Its Algebraic Operating System (AOS) helps maintain consistency during multi-step calculations. It is intended primarily for students studying pre-calculus and general mathematics.

The casing is made of grey plastic and includes a protective slide-on cover for the screen and buttons. The calculator is battery-powered and features an automatic shut-off to save energy. Three memory registers allow users to store and recall intermediate results, and a dedicated negation key allows for direct entry of negative values. The physical design focuses on classroom durability and straightforward operation.
