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.
In the MathPrint™ mode, you can enter up to four levels of
consecutive nested functions and expressions, which include
fractions, square roots, exponents with ^, Ê, ex, and 10x.
When you calculatean entry on the Home screen, depending

In Classic mode, fractions with qdo not allow operation
keys, functions, or complex fractions in the numerator or
denominator.
Note: In Classic mode, data editor, and table, use Wto
perform complex division problems.

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 qbetween the entry of the
numerator and the denominator.
•%N enters a mixed number. Press %N between
the entry of the unit and the numerator.
•% O converts betweenmixednumbersandsimple
fraction form.
•% j converts results between fractions and
decimals.

concentration of metal of 3% and 7300 tons with a
concentration of 2.3%. On the basis of these two extraction
figures, what is the total quantity of metal obtained?
If one ton ofmetal is worth 280 dollars, what is the total value
of the metal extracted?

Angle menu
%I
%I displays the choice of two submenus that enable
you to specify the angle unit modifier as degrees (º), minutes
('), seconds ("); radian (r); gradian (g), or convert units using
´DMS. You canalso convertbetweenrectangular coordinate
form (R) and polar coordinate form (P). (See Rectangular to
Polar for more information.)
Choose an angle mode from the mode screen. You can
choose from DEG (default), RAD, or GRAD. Entries are
