Texas Instruments TI36X Solar Scientific Calculator

10-Digit + 2 Exponent LCD screen : AnyLight solar powered : Calculates fractions : 1- and 2-variable statistics including standard deviations and linear regressions : 10 metric conversions : Base conversion and calculations (Decimal, Hexadecimal, Binary, Octal) : 15 Parentheses levels : 3 memories : 8 Physical constants : Up to 4 pending operations : Includes A76 battery (pre-installed), case and instructions

Ideal for students at every level, from junior high school algebra to college calculus, the Texas Instruments TI36 packs a lot of punch in a small, inexpensive unit. This solar-powered calculator combines features for statistical analysis, Boolean logic operations, and unit conversions in one sleek package.

Math students will appreciate TI36X's ability to perform fractional equations and calculate angle units (radians, grads, degrees) when performing trigonometric functions. Everyone will find the calculator's English/metric conversions helpful.

The TI36Xs single-line LCD is a little difficult to read when the unit is lying on a desk, and users in need of graphing functions will have to look elsewhere. Overall, however, for a calculator in this price range, the TI36X provides enough power for most high-level math and science needs.
