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 2 ⋅ ( 1 + 3 ) = ( 2 ⋅ 1 ) + ( 2 ⋅ 3 ) . {\displaystyle 2\cdot (1+3)=(2\cdot 1)+(2\cdot 3).}
The generalized distributive law (GDL) is a generalization of the distributive property which gives rise to a general message passing algorithm. [1] It is a synthesis of the work of many authors in the information theory, digital communications, signal processing, statistics, and artificial intelligence communities.
In the second step, the distributive law is used to simplify each of the two terms. Note that this process involves a total of three applications of the distributive property. In contrast to the FOIL method, the method using distributivity can be applied easily to products with more terms such as trinomials and higher.
For example, the law of distributivity can be proven as ... (where 0 is the identity element of the addition), and multiplication is distributive over addition. ...
In a non-distributive lattice, there may be elements that are distributive, but not dual distributive (and vice versa). For example, in the depicted pentagon lattice N 5, the element x is distributive, [2] but not dual distributive, since x ∧ (y ∨ z) = x ∧ 1 = x ≠ z = 0 ∨ z = (x ∧ y) ∨ (x ∧ z).
A completely distributive lattice L is called the free completely distributive lattice over a poset C if and only if there is an order embedding: such that for every completely distributive lattice M and monotonic function:, there is a unique complete homomorphism: satisfying =.
The Affordable Care Act’s chief aim is to extend coverage to people without health insurance. One of the 2010 law’s primary means to achieve that goal is expanding Medicaid eligibility to more people near the poverty level. But a crucial court ruling in 2012 granted states the power to reject the Medicaid expansion.
