Writing. Gregg shorthand is a system of phonography, or a phonemic writing system, which means it records the sounds of the speaker, not the English spelling. [4] For example, it uses the f stroke for the / f / sound in funnel, telephone, and laugh, [8] and omits all silent letters. [4] The system is written from left to right and the letters ...
A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a / b or , where a and b are both integers. [9] As with other fractions, the denominator ( b) cannot be zero. Examples include 1 2, − 8 5, −8 5, and 8 −5.
Canonical normal form. In Boolean algebra, any Boolean function can be expressed in the canonical disjunctive normal form ( CDNF ), [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 ...
Conjunctive normal form. Not to be confused with Chomsky normal form. In Boolean logic, a formula is in conjunctive normal form ( CNF) or clausal normal form if it is a conjunction of one or more clauses, where a clause is a disjunction of literals; otherwise put, it is a product of sums or an AND of ORs.
8 C 4 H 4 NH + 8 C 6 H 5 CHO + 3 O 2 → 2 (C 6 H 5 C) 4 (C 4 H 2 N) 2 (C 4 H 2 NH) 2 + 14 H 2 O. Despite its modest yields, the synthesis of H 2 TPP is a common experiment in university teaching labs. Highly efficient routes to H 2 TPP and many analogues involve the air-free condensation of the pyrrole and aldehyde to give the porphyrinogen ...
In mathematics and computer science, a canonical, normal, or standard form of a mathematical object is a standard way of presenting that object as a mathematical expression. Often, it is one which provides the simplest representation of an object and allows it to be identified in a unique way. The distinction between "canonical" and "normal ...
The 14 simplified components in Chart 2 are never used alone as individual characters. They only serve as components. Example of derived simplification based on the component 𦥯, simplified to 𰃮 ( ), include: 學 → 学; 覺 → 觉; 黌 → 黉. Chart 1 collects 352 simplified characters that generally cannot be used as components.
Basic English (a backronym for British American Scientific International and Commercial English) [1] is a controlled language based on standard English, but with a greatly simplified vocabulary and grammar. It was created by the linguist and philosopher Charles Kay Ogden as an international auxiliary language, and as an aid for teaching English ...
