  2. Canonical normal form - Wikipedia

    en.wikipedia.org/wiki/Canonical_normal_form

    In Boolean algebra, any Boolean function can be expressed in the canonical disjunctive normal form , [1] minterm canonical form, or Sum of Products (SoP or SOP) as a disjunction (OR) of minterms. The De Morgan dual is the canonical conjunctive normal form ( CCNF ), maxterm canonical form , or Product of Sums ( PoS or POS ) which is a ...

  3. Disjunctive normal form - Wikipedia

    en.wikipedia.org/wiki/Disjunctive_normal_form

    In boolean logic, a disjunctive normal form (DNF) is a canonical normal form of a logical formula consisting of a disjunction of conjunctions; it can also be described as an OR of ANDs, a sum of products, or — in philosophical logic — a cluster concept. [1] As a normal form, it is useful in automated theorem proving.

  4. Polynomial expansion - Wikipedia

    en.wikipedia.org/wiki/Polynomial_expansion

    In mathematics, an expansion of a product of sums expresses it as a sum of products by using the fact that multiplication distributes over addition. Expansion of a polynomial expression can be obtained by repeatedly replacing subexpressions that multiply two other subexpressions, at least one of which is an addition, by the equivalent sum of products, continuing until the expression becomes a ...

  5. Petrick's method - Wikipedia

    en.wikipedia.org/wiki/Petrick's_method

    P consists of a product of sums where each sum term has the form (+ + +), where each represents a row covering column . [ 7 ] Apply De Morgan's Laws to expand P {\displaystyle P} into a sum of products [ nb 1 ] and minimize by applying the absorption law X + X Y = X {\displaystyle X+XY=X} .

  6. Summation - Wikipedia

    en.wikipedia.org/wiki/Summation

    In mathematics, summation is the addition of a sequence of numbers, called addends or summands; the result is their sum or total.Beside numbers, other types of values can be summed as well: functions, vectors, matrices, polynomials and, in general, elements of any type of mathematical objects on which an operation denoted "+" is defined.

  7. Ordinal arithmetic - Wikipedia

    en.wikipedia.org/wiki/Ordinal_arithmetic

    The natural sum and natural product operations on ordinals were defined in 1906 by Gerhard Hessenberg, and are sometimes called the Hessenberg sum (or product) (Sierpiński 1958). The natural sum of α and β is often denoted by α ⊕ β or α # β, and the natural product by α ⊗ β or α ⨳ β. The natural sum and product are defined as ...

  8. Programmable logic array - Wikipedia

    en.wikipedia.org/wiki/Programmable_logic_array

    Preparation in SOP (sum of products) form. Obtain the minimum SOP form to reduce the number of product terms to a minimum. Decide the input connection of the AND matrix for generating the required product term. Then decide the input connections of the OR matrix to generate the sum terms. Decide the connections of the inversion matrix. Program ...

    Formally, if one expands () (), the terms are precisely (), where is either 0 or 1, accordingly as whether is included in the product or not, and k is the number of that are included, so the total number of factors in the product is n (counting with multiplicity k) – as there are n binary choices (include or x), there are terms ...
