is this a valid statement
[itex]\overline{A\overline{B}} = \overline{A}B[/itex]
[itex]\overline{A\overline{B}} = \overline{A}B[/itex]
barryj said:I seem to recall a rule something like not(AB) = A' + B' and not(A+B) = A'B'
Don't remember the name however.

Boolean Algebra is a mathematical system used for logical operations and is named after mathematician George Boole. It consists of only two values, True (represented by 1) and False (represented by 0), and uses logical operators such as AND, OR, and NOT to manipulate these values.
Negation, also known as complement or inversion, is an operation in Boolean Algebra that changes the value of an input. It takes a single input and produces the opposite value. For example, the negation of True is False, and the negation of False is True.
A quickie in Boolean Algebra refers to the process of applying negation to a Boolean expression. This involves changing all True values to False and vice versa, as well as applying the negation operation to any logical operators within the expression.
Negation is used in Boolean Algebra to create the logical complement of a given value or expression. This is helpful in simplifying complex logical expressions and in creating truth tables to determine the validity of logical arguments.
Negation is represented by the symbol "¬" or the tilde "~" and is placed before the input or expression being negated. For example, the negation of A would be written as ¬A or ~A.
