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.
In the MathPrint™ mode, you can enter up to four levels
of consecutive nested functions and expressions,
which include fractions, square roots, exponents with
^, Ü, e
x
, and 10
x
.
When you calculate an entry on the Home screen,
depending upon space, the answer is displayed either
directly to the right of the entry or on the right side of
the next line.
Special indicators and cursors may display on the
screen to provide additional information concerning
functions or results.

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
1.2345678×10
5
).
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: E is a shortcut key to enter a number in
scientific notation format. The result displays in
the numeric notation format selected in the mode
menu.

functions sin and sin/ as wellas the hyperbolic
functions sinh and sinh/. Press the key repeatedly to
display the function that you want to enter.
Multi-tap keys include z, X, Y, Z, C, D,
H, and g. Applicable sections of this guidebook
