Proposition | Assertion | Predicate | A proposition is the contents of an assertion which can be true or false. One of two propositions contains a term called a predicate that can be used to support the conclusion of a syllogism. Sep 9, 2016 https://philosophy.stackexchange.com If all of a predicate' s variables are bound, the resulting formula is a proposition. (WikiDiff) an instance of a ' predicate whose terms are all constant — e.g., P(2,3) — acts as a proposition. | |
Assertion | Predicate | True result; Affirmation | Proposition | assertion is (computing) a statement in a program asserting a condition expected to be true at a particular point. https://wikidiff.com/predicate/assertion |
Predicate | Expression, Term | Proposition | A predicate is (computing) an operator or function that returns either true or false. (Wikidiff) (logic) To state, assert. (logic) A term of a statement, where the statement may be true or false depending on whether the thing referred to by the values of the statement's variables has the property signified by that (predicative) term. A nullary predicate''' is a proposition. A predicate is either valid, satisfiable, or unsatisfiable. There are two ways of binding a predicate's variables: one is to assign constant values to those variables, the other is to quantify over those variables (using universal or existential quantifiers). If all a predicate' s variables are bound, the resulting formula is a proposition. | |
Expression | Term (1 or more) | Predicate | In mathematics the difference between expression and term is that expression is (mathematics) an arrangement of symbols denoting values, operations performed on them, and grouping symbols while term is (mathematics) any value (variable or constant) or expression separated from another term by a space or an appropriate character, in an overall expression or table. | |
Term | Expression | 1 Term (parenthesized expressions can be treated as terms) | Predicate | (mathematics) Any value (variable or constant) or expression separated from another term by a space or an appropriate character, in an overall expression or table. (logic) The subject or the predicate of a proposition; one of the three component parts of a syllogism, each one of which is used twice. |
