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.

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,
