- 10-digit display; for general math, pre-algebra, algebra 1 and 2, trigonometry and biology
- Performs trigonometric functions, logarithms, roots, powers, reciprocals, and factorials
- Also add, subtract, multiply and divide fractions; 1-variable statistics (mean / standard deviation)
- Conversions: fractions/decimals, degrees/radians/grads, DMS/decimal/degrees, and polar/rectangular
- Battery-powered; includes slide case
- Ideal for general math, pre-algebra, algebra I and II and general science.
- Adds, subtracts, multiplies, and divides fractions entered in traditional numerator/denominator format

Once you get to a certain level of math classes, a regular old calculator just isn't good enough anymore--you need a high-functioning calculator that can perform algebraic, trigonometric, and statistical problems in addition to general mathematical tasks. The Texas Instruments TI-30XA scientific calculator can do this for you. It is extremely handy when it comes to figuring tricky fractions. It can add, subtract, multiply, and divide fractions when entered in a traditional numerator/denominator format. This calculator can also do a variety of conversions, from fractions to decimals, degrees to radians to grads, DMS to decimal to degrees, and polar to rectangular. The display screen holds up to 10 digits.

For high school or college students tackling advanced math, this is a great tool (and a thoughtful back-to-school gift), and with more professors allowing the use of calculators during classes and exams, it's a necessary one. Easy to use and easy to slip into a backpack, the TI-30XA will soon become indispensable for both the serious and the striving math student. --Dana Van Nest
