Examples Each section is followed by instructions for keystroke examples that demonstrate the TI-30XS MultiView™ and TI-30XB MultiView functions. All references in this manual will refer to the TI-30XS MultiView, but are also applicable for the TI-30XB MultiView. Examples assume all default settings, as shown in the Modes section. For more activities and examples, see the TI-30XS MultiView™ Teacher Guide available at education.ti.com/ guides.
Home screen On the Home screen, you can enter mathematical expressions and functions, along with other instructions. The answers are displayed on the Home screen. The TI-30XS MultiView screen can display a maximum of four lines with a maximum of 16 characters per line. For entries and expressions of more than 16 characters, you can scroll left and right (!and ") to view the entire entry or expression.
¹ ¸ An entry or menu displays beyond 16 digits. Press ! or " to scroll. 2nd functions % Most keys can perform two functions. The primary function is indicated on the key and the secondary function is displayed above it. Press % to activate the secondary function of a given key. Notice that 2nd appears as an indicator on the screen. To cancel it before entering data, press % again. For example, % b 25 < calculates the square root of 25 and returns the result, 5. Modes p Use pto choose modes.
Note: In some restricted environments (for example function table, data editor, and the %h menu), the TI-30XS MultiView™ calculator may display E instead of Ã10n. ENG displays results as a number from 1 to 999 times 10 to an integer power. The integer power is always a multiple of 3. Note: C is a shortcut key to enter a number in scientific notation format. The result displays in the numeric notation format set in mode. FLOAT 0123456789 Sets the decimal notation mode.

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.
