1. That which is considered and established as a principle; hence, sometimes, a rule.

Not theories, but theorems (&?;), the intelligible products of contemplation, intellectual objects in the mind, and of and for the mind exclusively.
Coleridge.

By the theorems,
Which your polite and terser gallants practice,
I re-refine the court, and civilize
Their barbarous natures.
Massinger.

2. (Math.) A statement of a principle to be demonstrated.

&fist; A theorem is something to be proved, and is thus distinguished from a problem, which is something to be solved. In analysis, the term is sometimes applied to a rule, especially a rule or statement of relations expressed in a formula or by symbols; as, the binomial theorem; Taylor's theorem. See the Note under Proposition, n., 5.
