  2. Associative property - Wikipedia

    en.wikipedia.org/wiki/Associative_property

    Associative property. In mathematics, the associative property[ 1] is a property of some binary operations that means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs .

  3. Associative algebra - Wikipedia

    en.wikipedia.org/wiki/Associative_algebra

    e. In mathematics, an associative algebra A over a commutative ring (often a field) K is a ring A together with a ring homomorphism from K into the center of A. This is thus an algebraic structure with an addition, a multiplication, and a scalar multiplication (the multiplication by the image of the ring homomorphism of an element of K ).

  4. Commutative property - Wikipedia

    en.wikipedia.org/wiki/Commutative_property

    In mathematics, a binary operation is commutative if changing the order of the operands does not change the result. It is a fundamental property of many binary operations, and many mathematical proofs depend on it. Perhaps most familiar as a property of arithmetic, e.g. "3 + 4 = 4 + 3" or "2 × 5 = 5 × 2", the property can also be used in more ...

    en.wikipedia.org/wiki/Algebra_of_sets

    Fundamentals. The algebra of sets is the set-theoretic analogue of the algebra of numbers. Just as arithmetic addition and multiplication are associative and commutative, so are set union and intersection; just as the arithmetic relation "less than or equal" is reflexive, antisymmetric and transitive, so is the set relation of "subset".

  6. Abelian group - Wikipedia

    en.wikipedia.org/wiki/Abelian_group

    In mathematics, an abelian group, also called a commutative group, is a group in which the result of applying the group operation to two group elements does not depend on the order in which they are written. That is, the group operation is commutative. With addition as an operation, the integers and the real numbers form abelian groups, and the ...

  7. Distributive property - Wikipedia

    en.wikipedia.org/wiki/Distributive_property

    Distributive property. In mathematics, the distributive property of binary operations is a generalization of the distributive law, which asserts that the equality is always true in elementary algebra . For example, in elementary arithmetic, one has Therefore, one would say that multiplication distributes over addition .

  8. Operator associativity - Wikipedia

    en.wikipedia.org/wiki/Operator_associativity

    Operator associativity. In programming language theory, the associativity of an operator is a property that determines how operators of the same precedence are grouped in the absence of parentheses. If an operand is both preceded and followed by operators (for example, ^ 3 ^ ), and those operators have equal precedence, then the operand may be ...

  9. Property (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Property_(mathematics)

    In mathematics, a property is any characteristic that applies to a given set. [1] Rigorously, a property p defined for all elements of a set X is usually defined as a function p: X → {true, false}, that is true whenever the property holds; or, equivalently, as the subset of X for which p holds; i.e. the set { x | p ( x ) = true}; p is its ...
