Examples Each section is followed by instructions for keystroke examples that demonstrate the TI-30X Plus MultiView™ functions. Examples assume all default settings, as shown in the Modes section. Some screen elements may differ from those shown in this document. Switching the calculator on and off & turns on the calculator.% ' turns it off. The display is cleared, but the history, settings, and memory are retained.
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-30X Plus 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.

NORM SCI ENG Sets the numeric notation mode. Numeric notation modes affect only the display of results, and not the accuracy of the values stored in the unit, which remain maximal. NORM displays results with digits to the left and right of the decimal, as in 123456.78. SCI expresses numbers with one digit to the left of the decimal and the appropriate power of 10, as in 1.2345678×5 (which is the same as 1.2345678×105). ENG displays results as a number from 1 to 999 times 10 to an integer power.

Errors When the calculator detects an error, it returns an error message with the type of error. The following list includes some of the errors that you may encounter. To correct the error, note the error type and determine the cause of the error. If you cannot recognize the error, refer to the following list. Press - to clear the error message. The previous screen is displayed with the cursor at or near the error location. Correct the expression.
• For a function (including implied multiplication) or an instruction, you entered an argument that is an invalid data type, such as a complex number where a real number is required. • You attempted to store an incorrect data type, to a list. • Input to the complex conversions is real. • You attempted to execute a complex number in an area that is not allowed. DIM MISMATCH — You get this error if • you attempt to store a data type with a dimension not allowed in the storing data type.
EQUATION LENGTH ERROR — An entry exceeds the digit limits (80 for stat entries or 47 for constant entries); for example, combining an entry with a constant that exceeds the limit. Exponent must be Integer — This error is returned if the exponent is not an integer. FORMULA — The formula does not contain a list name (L1, L2, or L3), or the formula for a list contains its own list name. For example, a formula for L1 contains L1. FRQ DOMAIN — FRQ value (in 1-Var and 2-Var stats) < 0.
INVALID FUNCTION — An invalid function is entered in the function definition in Function table. Mean mu>0 — An invalid value is input for the mean (mean = mu) in poissonpdf or poissoncdf. Number of trials 0
TOO COMPLEX — If you use too many levels of MathPrint™ complexity in a calculation, the TOO COMPLEX error is displayed (this error is not referring to complex numbers). LOW BATTERY — Replace the battery. Note: This message displays briefly and then disappears. Pressing - does not clear this message.
Battery information Battery precautions • Do not leave batteries within the reach of children. • Do not mix new and used batteries. Do not mix brands (or types within brands) of batteries. • Do not mix rechargeable and non-rechargeable batteries. • Install batteries according to polarity (+ and -) diagrams. • Do not place non-rechargeable batteries in a battery recharger. • Properly dispose of used batteries immediately. • Do not incinerate or dismantle batteries.
• With a small screwdriver, remove the screws from the back of the case. • From the bottom, carefully separate the front from the back. Be careful not to damage any of the internal parts. • With a small screwdriver (if required), remove the battery. • To replace the battery, check the polarity (+ and -) and slide in a new battery. Press firmly to snap the new battery into place. Important: When replacing the battery, avoid any contact with the other components of the calculator.
