  2. Boolean algebra - Wikipedia

    en.wikipedia.org/wiki/Boolean_algebra

    Boolean algebra is therefore a formal way of describing logical operations in the same way that elementary algebra describes numerical operations. Boolean algebra was introduced by George Boole in his first book The Mathematical Analysis of Logic (1847), [1] and set forth more fully in his An Investigation of the Laws of Thought (1854). [2]

  3. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    The order of operations, that is, the order in which the operations in an expression are usually performed, results from a convention adopted throughout mathematics, science, technology and many computer programming languages. It is summarized as: [2] [5] Parentheses; Exponentiation; Multiplication and division; Addition and subtraction

  4. Boolean algebra (structure) - Wikipedia

    en.wikipedia.org/wiki/Boolean_algebra_(structure)

    In abstract algebra, a Boolean algebra or Boolean lattice is a complemented distributive lattice. This type of algebraic structure captures essential properties of both set operations and logic operations. A Boolean algebra can be seen as a generalization of a power set algebra or a field of sets, or its elements can be viewed as generalized ...

  5. Boolean algebras canonically defined - Wikipedia

    en.wikipedia.org/wiki/Boolean_algebras...

    Boolean algebra is a mathematically rich branch of abstract algebra. Stanford Encyclopaedia of Philosophy defines Boolean algebra as 'the algebra of two-valued logic with only sentential connectives, or equivalently of algebras of sets under union and complementation.' [1] Just as group theory deals with groups, and linear algebra with vector spaces, Boolean algebras are models of the ...

  6. List of logic symbols - Wikipedia

    en.wikipedia.org/wiki/List_of_logic_symbols

    propositional logic, Boolean algebra, first-order logic ⊤ {\displaystyle \top } denotes a proposition that is always true. The proposition ⊤ ∨ P {\displaystyle \top \lor P} is always true since at least one of the two is unconditionally true.

  7. Truth table - Wikipedia

    en.wikipedia.org/wiki/Truth_table

    A truth table is a mathematical table used in logic—specifically in connection with Boolean algebra, Boolean functions, and propositional calculus—which sets out the functional values of logical expressions on each of their functional arguments, that is, for each combination of values taken by their logical variables. [1]

  8. Two-element Boolean algebra - Wikipedia

    en.wikipedia.org/wiki/Two-element_Boolean_algebra

    In a four-element Boolean algebra whose domain is the powerset of ⁠ {,} ⁠, this formula corresponds to the statement (x = ∅) ∨ (x = {0,1}) and is false when x is ⁠ {} ⁠. The decidability for the first-order theory of many classes of Boolean algebras can still be shown, using quantifier elimination or small model property (with the ...

  9. Boolean function - Wikipedia

    en.wikipedia.org/wiki/Boolean_function

    A Boolean function is a Sheffer function if it can be used to create (by composition) any arbitrary Boolean function (see functional completeness) The algebraic degree of a function is the order of the highest order monomial in its algebraic normal form
