Editing Category:Theorems (section)

{{Commons category}}
{{Cat main|Theorem}}

The concepts described in articles in this category may be also expressed in terms of [[:Category:Arguments|arguments]], or [[:Category:Rules of inference|rules of inference]]. Very often the same concept is in more than one of these categories, expressed a different way and sometimes with a different name. Please also observe that a '''[[theorem]]''' is distinct from a [[:Category:Theories|theory]]. A [[:Category:Lemmas|lemma]] is conceptually the same as a theorem. However a theorem is called a lemma when its proof is only considered to be a step in the proof of some other, more important theorem.
