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", "product_information": {"ASIN": "B00000JBNS", "Batteries": "1 Lithium Metal batteries required.", "Department": "Office Machines and Supplies", "Item Weight": "3.7 ounces", "Manufacturer": "Texas Instruments", "Best Sellers Rank": "#3,010 in Office Products (See Top 100 in Office Products) #5 in Scientific Calculators", "Item model number": "30XA/TBL/1L1/K", "Product Dimensions": "5.91 x 2.95 x 0.51 inches", "Date First Available": "July 7, 2004", "Is Discontinued By Manufacturer": "No"}, "product_details": {"Brand": "Texas Instruments", "Color": "Gray", "Screen Size": "3", "Power Source": "Battery Powered", "Calculator Type": "Engineering/Scientific"}}
