  2. Van Hiele model - Wikipedia

    en.wikipedia.org/wiki/Van_Hiele_model

    The object of thought is deductive reasoning (simple proofs), which the student learns to combine to form a system of formal proofs (Euclidean geometry). Learners can construct geometric proofs at a secondary school level and understand their meaning. They understand the role of undefined terms, definitions, axioms and theorems in

  3. Deductive reasoning - Wikipedia

    en.wikipedia.org/wiki/Deductive_reasoning

    This theory of deductive reasoning – also known as term logic – was developed by Aristotle, but was superseded by propositional (sentential) logic and predicate logic. [citation needed] Deductive reasoning can be contrasted with inductive reasoning, in regards to validity and soundness. In cases of inductive reasoning, even though the ...

  4. Deduction theorem - Wikipedia

    en.wikipedia.org/wiki/Deduction_theorem

    In practice, it is usually enough to know that we could do this. We normally use the natural-deductive form in place of the much longer axiomatic proof. First, we write a proof using a natural-deduction like method: Q 1. hypothesis Q→R 2. hypothesis; R 3. modus ponens 1,2 (Q→R)→R 4. deduction from 2 to 3; Q→((Q→R)→R) 5. deduction ...

  5. Natural deduction - Wikipedia

    en.wikipedia.org/wiki/Natural_deduction

    In logic and proof theory, natural deduction is a kind of proof calculus in which logical reasoning is expressed by inference rules closely related to the "natural" way of reasoning. [1] This contrasts with Hilbert-style systems, which instead use axioms as much as possible to express the logical laws of deductive reasoning.

  6. Mathematics - Wikipedia

    en.wikipedia.org/wiki/Mathematics

    In the 19th century, the internal development of geometry (pure mathematics) led to definition and study of non-Euclidean geometries, spaces of dimension higher than three and manifolds. At this time, these concepts seemed totally disconnected from the physical reality, but at the beginning of the 20th century, Albert Einstein developed the ...

  7. Formal system - Wikipedia

    en.wikipedia.org/wiki/Formal_system

    Deductive system, deductive apparatus, or proof system, which has rules of inference that take axioms and infers theorems, both of which are part of the formal language. A formal system is said to be recursive (i.e. effective) or recursively enumerable if the set of axioms and the set of inference rules are decidable sets or semidecidable sets ...

  8. Argument–deduction–proof distinctions - Wikipedia

    en.wikipedia.org/wiki/Argument–deduction...

    The reasoning in a deduction is by definition cogent. Such reasoning itself, or the chain of intermediates representing it, has also been called an argument, more fully a deductive argument . In many cases, an argument can be known to be valid by means of a deduction of its conclusion from its premises but non-deductive methods such as Venn ...
