Logical and Negation Operations
Logical and negation operations are performed by pressing  and then
selecting the desired command (and, or, xor, xnor, Not, Neg) from the menu

((BIN)).
To determine the logical AND of 1010
To determine the bitwise complement of 1010
Note: In the case of a negative binary, octal or hexadecimal value, the
calculator converts the value to binary, takes the two's complement, and
then converts back to the original number base. For decimal values, the
calculator merely adds a minus sign.
