The TI-30XS MultiView™ calculator defaults output to improper fractions. Results are automatically simplified. • q enters a simple fraction. Pressing q before or after a number can result in different behavior. Entering a number before pressing q makes that number the numerator. To enter fractions with operators or radicals, press q before you enter a number (in MathPrint™ mode only). In MathPrint mode, press $ between the entry of the numerator and the denominator. In Classic mode, press q
