The TI-30X IIS is a scientific calculator capable of performing various functions, including general math problems such as fractions. The calculator can work with a simple fraction, such as ¾, or a mixed fraction, such as 3 2/3. Unless otherwise specified, the calculator provides an answer containing fractions. To do fractions on the calculator, the numbers must be entered a certain way to ensure the calculator accurately performs the calculations.
