Produktbeschreibung

High Quality Content by WIKIPEDIA articles! In the formal languages used in mathematical logic and computer science, a well-formed formula or simply formula (often abbreviated wff, pronounced "wiff" or "wuff") is an idea, abstraction or concept which is expressed using the symbols and formation rules (also called the formal grammar) of a particular formal language. To say that a string of symbols S is a wff with respect to a given formal grammar G is equivalent to saying that S belongs to the language generated by G. A formal language can be identified with the set of its wffs. Although the term "well-formed formula" is commonly used to refer to the written marks, for instance, on a piece of paper or chalkboard which are being used to express an idea; it is more precisely understood as the idea being expressed and the marks as a token instance of the well formed formula. Two different strings of marks may be tokens of the same well-formed formula. This is to say that there may bemany different formulations of the same the idea.
