On and Off
O
turns the calculator on;
$
[
OFF
] turns it
off.
The calculator automatically turns off if no key is pressed for 9
minutes. Press
O
to reactivate the calculator. The display,
memory, and settings are retained.
Display
The display comprises the entry line, the result line,
and indicators.
Entry Line
You can enter up to 80 characters. Your entry
scrolls to the left°and the
–
indicator is displayed°when you
enter 11 or more characters.
By default, the calculator is in
overwrite
mode
. In overwrite
mode the cursor is the underscore character (_) and any digit
you enter appears at the cursor±s position. If there is a digit
below the cursor, that digit is replaced by your new entry.
You can also set the calculator to
insert mode
. In insert mode
the cursor appears as
·
and any digit you enter is inserted to
the left of the cursor. To activate insert mode, place the cursor
where you want to insert a character and press
$
[
INS
]. To
deactivate insert mode, press an arrow key or
$
[
INS
] again.
Press
p
or
/
to move the cursor through an entry. To go
directly to the first character, press
$/
. To go directly to the
last character, press
$p
. To delete a digit, press
e
(or, in
overwrite mode, just type over the digit).
Negative Numbers
To enter a negative number, press
F
before entering the digits.
Result Line
The result of a calculation is displayed on the
result line (the bottom line of the display). Up to 10 digits can be
displayed, as well as a negative sign, decimal point, the
°
10
indicator, and a positive or negative exponent. Calculation
accuracy is up to 24 decimal places.
Indicators
These are displayed to indicate certain
selections, states, or settings (see table below).
Order of Entry
You enter numbers and operators in the
same order as you write them in traditional arithmetic.
2
nd
Functions
Functions represented by the labels on the
faceplate are selected by first pressing
$
and then the key
below the label. For example, to select the % function, press
$-
. (In this guide, labels are enclosed in square brackets.
For example, an instruction to select the % function is indicated
by
$
[%].)
Menus
Many functions and settings are available on menus.
A menu is a list of options displayed across the entry line. For
example, pressing
$
[
SCI
/
ENG
] displays the menu for
choosing the number display.
Choose an item from a menu by pressing
p
or
/
until the
item is underlined, and then press
\
.
To cancel a menu without choosing an item, press
U
.
Modes
There are four modes (or operating environments):
n
0. Home (the default mode, used for common calculations)
n
1. Statistics (
STAT
)
n
2. Linear equation solver (
L
SOLV
)
n
3. Quadratic equation solver (
Q
SOLV
).
Press
!
to display the Modes menu. To select a mode, press
the number of the mode. Alternatively, press
p
or
/
until the
mode you want is underlined and then press
\
.
Contrast
To change the display contrast, press
!
and
then
n
or
o
as many times as is necessary. Press
U
to
close the Modes menu.
Previous Entries
The HP 30S keeps a record of all the
entries you make (up to a maximum of 320 characters). These
entries are retained even if you turn off the calculator.
Press
n
or
o
to scroll through the entries. You can reuse or
edit a previous entry when it is on the entry line.
Last answer
The last answer is stored automatically in
memory. It is kept even if you turn the calculator off.
To retrieve the last answer, press
$
[
ANS
].
Ans
appears on the
entry line. Press
\
to see the value of the last answer.
You can also use the last answer in a new calculation by first
pressing an operator key (
+
,
-
, etc).
Ans
appears on the
entry line followed by the operator. You then complete the entry
as you would normally.
Linear Solutions
The results of solving a set of linear
equations are stored in the variables
X
and
Y
.
Quadratic Solutions
The results of solving a quadratic
equation are stored in the variables
X
1
and
X
2
,
or
Y
1
and
Y
2
.
Memory variables
There are five memory variables:
A
,
B
,
C
,
D
, and
EQN
. You can store real numbers in variables
A
²
D
,
and store an expression in
EQN
.
You can also store real numbers in
X
,
Y
,
X
1
, X
2
, Y
1
,
and
Y
2
;
however, the values in these variables are replaced with linear
equation and quadratic solutions.
You store a number or expression in a variable by entering it,
pressing
?
, selecting the variable from the Variables menu,
and pressing
\
.
Constant expression [K]
A constant expression is any
combination of operators, functions, variables, and numbers
that can be added to the end of an entry and be evaluated. A
constant expression is useful if you want to apply the same
operation many times to different inputs.
To define (or modify) the constant expression, press
$
[
K
],
enter the operators, functions, and numbers that you need, and
press
\
.
To use the constant expression, the
K
indicator needs to be
displayed. (If it is not displayed, press
$
[
K
].) Pressing
\
will now attach the constant expression to your input and
evaluate the result. For example, if your constant expression is
³+ sin(30)´, entering 2 and pressing
\
yields 2.5, that is,
2 + sin(30).
To return to normal operation, press
$
[
K
] again. The constant
expression is retained for later use.
Running memory
Press
#
to add a result to running
memory. Press
;
