the following functions :
nPr
Calculates the number of possible permutations of n item taken
r at a time.
nCr
Calculates the number of possible combinations of n items
taken r at a time.
! Calculates the factorial of a specified positive integer n ,
where n 69.

] ) and exponentiation ( [ ^ ] ) functions.
See Example 35.
2 - 15 Unit Conversion
• The calculators has a built-in unit conversion feature that enables you to
convert numbers from metric to English units and vice versa. See Example
36.
1. Enter the number you want to convert.
2. Press [ 2nd ] [ CONV ] to display the menu. There are 7 menus,
covering distance, area, temperature, capacity, weight, energy, and
pressure.
3. Use the [] [] to scroll through the list of units until a appropriate
units menu is shown, then [ ENTER ].
4. Pressing [] or [] can convert the number to another unit.
2 - 16 Physics constants
You can use a number physics constants in your calculations. With the
following constants :

To insert a constant at the cursor position ( See Example 37.) :
1. Press [ CONST ] to display the physics constants menu.
2. Press [] until the constant you want is underlined.
3. Press [ ENTER ].
3 Mode 1 - STAT
There are three menu operation in statistics menu :
1 -VAR
( for analyzing
data in a single dataset),
2 - VAR
( for analyzing paired data from two
datasets ) and
CLR- DATA
( for clearing all datasets). See Example 38.
To enter data for statistical analysis :
1. From the statistics menu, choose
1 -VAR
or
2 - VAR.
2. Press [ DATA ].
3. Enter an X - values and press [].
4. Enter the frequency ( FREQ for SRP-280 / F for SRP-285) of the X
- value (in
1 -VAR
mode) or the corresponding Y - value ( in
2 - VAR
mode ) and press [].
5. To enter more data, repeat from step 3.
To analyze data you have entered :
1. Press [ STATVAR ]. A range of statistical variables (see table
below ) is displayed on the statistical result menus. The first
variable ( n ) is underlined and its value is on the result line.
2. Press [] to scroll through the statistical results menu. The value
of each variable is displayed on the result line.
3. To use a value in a calculation, press [ ENTER ] when the values
is displayed. The values is copied to the entry line.
4. To predict a value for x ( or y ) given a value for y ( or x ), select the
x ’ ( or y ’ ) variable, press [ ENTER ], enter the given value, and
press [ ENTER ] again.
Variable Meaning
n Number of x values or x-y pairs entered.
__
x or y Mean of the x values or y values
Sx or Sy Sample standard deviation of x values or y values.

r Correlation coefficient
x ’ Predicted x values given a, b, and a y values
y ’ Predicted y value given a, b, and x value.
(Note) : If an error message appears in the display under STATVAR menu,
just pressing [] or [] can continue viewing next statistical vari-
able value.
To view or change data :
1. Press [ DATA ].
2. Press [] to scroll through the data you have entered.
3. To change an entry, display it and enter the new data. The new data
you enter overwrites the old entry. Press [] or [ ENTER ] to save the
change.
(Note) : Even you exit STAT mode, all data in
1 - VAR
and
2 - VAR
mode
are still retained unless you clear all data by selecting
CLR - DATA
mode.
4 Mode 2 - Base-n
4 - 1 Bases conversions
• The number system (10, 16, 2 , 8 ) is set by pressing [ 2nd ] [ dhbo ] to display
the menu, making one of the items underlined followed [ ENTER ]. A
corresponding symbol - “d ”, “h”, “b”, “o” appears on the display. (The
default setting is d : decimal base). See Example 39.
(Note) : The total range of numbers handled in this mode is 0, 1, 2, 3, 4, 5,
6, 7, 8, 9, A, B, C, D, E, F. If values not valid for the particular number
system are used, attach the corresponding designator (d, h, b, o),
or an error message will appear.
Binary base ( b ) : 0, 1
Octal base ( o ) : 0, 1, 2, 3, 4, 5, 6, 7
Decimal base ( d ) : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Hexadecimal base ( h ) : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
• Pressing [ ] can use block function to display a result in octal or binary
base which exceeds 8 digits. The system is designed to display up to 4
blocks. See Example 40.

2 - 15 Umwandlung in andere Einheiten
• Der Taschenrechner besitzt eine eingebaute Funktion zur Umrechnung
in andere Einheiten, mit der Sie metrische Zahlen in andere Einheiten
umwandeln können und umgekehrt. Vgl. Beispiel 36
1. Geben Sie die Zahl ein, die umgewandelt werden soll.
2. Drücken Sie [ 2nd ] [ CONV ], um in den entsprechenden Mode zu
gelangen. Dieses enthält sieben Angaben: Umrechnung von
Entfernungen, Flächen, Temperaturen, Volumen, Gewichten, Energie
und Druck.
3. Benutzen Sie [] [], um in der Liste nach der gewünschten Einheit
zu suchen. Dann drücken Sie [ ENTER ].
4. Drücken Sie [] oder [], um Zahlen in andere Einheiten
umzuwandeln.

4 - 3 Grundlegende arithmetische
Berechnungen für Basen
• Sie können mit dem Taschenrechner in anderen Basen als der des
Zehnersystems rechnen. Sie können binäre, oktale und hexadezimale Zahlen
addieren, subtrahieren, multiplizieren und dividieren. Vgl. Beispiel 42
4 - 4 Logische Berechnungen
• Logische Berechnungen können durch logische Produkte (AND), nega-
tive logische Berechnungen (NAND), logische Summen (OR), exklusive
logische Summen (XOR), Negationen (NOT), und die Negation exklusiv
logischer Summen erfolgen (XNOR). Vgl. Beispiel 43
5 Mode 3 - CPLX
• Der Mode für komplexe Zahlen (CPLX) erlaubt eine Addition, Subtraktion,
Muotiplikation und Division komplexer Zahlen. Vgl. Beispiel 44 Das
Ergebnis einer Rechenoperation mit komplexen Zahlen kann wie folgt
dargestellt werden:
Re Realwert Im Imaginärer Wert
ab Absoluter Wert ar Argument-Wert
6 Mode 4 - VLE
Der Mode für variable lineare Gleichungen (VLE) erlaubt die
Berechnung eines Sets von simultanen Größen mit zwei Unbekannten wie
folgt:
a x + b y = c
d x + e y = f, dabei sind x und y unbekannt.
• Im Mode VLE geben Sie einfach die Koeffizienten ( a, b, c, d, e, f ) in der
richtigen Reihenfolge ein. Der Taschenrechner berechnet dann automatisch
die Werte für x und y. Vgl. Beispiel 45
7 Mode 5 - QE
Der Mode für quadratische Gleichungen (QE) kann folgende
Rechenoperationen lösen:
a x
2
+ b x + c = 0, wobei x unbekannt sind.
• Im Mode QE geben Sie einfach die Koeffizienten ( a, b, c ) in der
richtigen Reihenfolge ein. Der Taschenrechner berechnet automatisch
die Werte für x. Vgl. Beispiel 46
