Negative expressions
In binary, octal, and hexadecimal bases, the calculator represents
negative numbers using complement notation. The complement is the
result of subtracting that number from 10000000000 in that number's
base by pressing [ NEG ] key in non-decimal bases.

Logical operation
Logical operations are performed through logical products (AND),
negative logical (NAND), logical sums (OR), exclusive logical sums
(XOR), negation (NOT), and negation of exclusive logical sums
(XNOR).

Statistical Calculations
Use STAT ( [ MODE ] 2 ( STAT ) ) mode for statistical calculations.
The calculators can perform both single–variable statistical
calculations and paired–variable in this mode.
Press [ MODE ] 2 ( STAT ) to enter STAT mode. There are six items in
STAT mode, asking you to select one of them,

Single–variable statistics
1–VAR Single–variable statistics
Paired-variable / Regression statistics
LIN Linear Regression y = a + b x
LOG Logarithmic Regression y = a + b lnx
EXP Exponential Regression y = a • e
bx
POW Power Regression y = a • x
b
D–CL Clear all statistical data
Entering data
Always make sure you clear statistical data by D–CL before
performing statistical calculations.
(A) To input single–variable data using the following syntaxes :
# Individual data : [ DATA ] < x value >
# Multiple data of the same value :
[ DATA ] < x value > [ x ] < Number of repeats >
(B) To input paired–variable / regression data using the following
syntaxes :
# Individual data-set : [ DATA ] < x value > [
] < y value >
# Multiple data of the same value :
[ DATA ] < x value > [
] < y value > [ x ] < Number of repeats >
(Note) : Even you exit STAT mode, all data are still retained unless
you clear all data by selecting D-CL mode.
Displaying results
The values of the statistical variables depend on the data you input.
You can recall them by the key operations shown in the below table.
Single–variable statistics calculations
Variables Meaning
n ( [ n ] ) Number of the x values entered
x
( [2nd]+[
x
] ) Mean of the x values
Sx ( [2nd]+[
