		When the glue is dry, you can now start turning the ring inside-out, pushing the center up from the bottom, and the outside parts down.

	Ring (mathematics) (Site not responding. Last check: )
		In mathematics, a ring is an algebraic structure in which addition and multiplication are defined and have similar (but not identical) properties to those familiar from the integers.
		Rings that also satisfy commutativity for multiplication (such as the ring of integers) are called commutative rings.
		The center of a ring R is the set of elements of R that commute with every element of R; that is, c lies in the center if cr=rc for every r in R.

	AllRefer.com - ring, mathematical system (Mathematics) - Encyclopedia
		ring, in mathematics, system consisting of a set R of elements and two binary operations, such that addition makes R a commutative group and multiplication is associative and distributes over addition (see commutative law; associative law; distributive law).
		A commutative ring is one in which the commutative law also holds for multiplication.
		Examples of commutative rings are the sets of integers (see number) and real numbers.

	Algebraic Areas of Mathematics
		We have included here the combinatorial topics and number theory; each is arguably a distinctive area of mathematics but (as the MathMap suggests) these parts of mathematics, shown in shades of red, share definite affinities.
		The use of algebra is pervasive in mathematics.
		Of particular interest are several classes of rings of interest in number theory, field theory, algebraic geometry, and related areas; however, other classes of rings arise, and a rich structure theory arises to analyze commutative rings in general, using the concepts of ideals, localizations, and homological algebra.

		If R is a unital ring, then the left multiplications by elements of R obviously form endomorphisms of the additive group of R. In fact they form a group direct summand of the endomorphism ring and if the complement is trivial, then these rings are called E-rings which are well-studied.
		Finally, we show that in ZFC there exists an almost-free ring R of minimal uncountable cardinality such that the endomorphism ring of R is isomorphic to the direct sum of the integers and R itself.

		For the purposes of this note, rings are associative with unit element, and 'Noetherian' means that the maximum condition holds for left and right ideals.
		For a simple Noetherian ring, the requirement is just that every left and right ideal should be a projective module; this condition is satisfied by all simple rings with minimum condition, and by some without it.
		The endornorphism ring of P is a simple Noetherian ring, which has zero-divisors in general.

		Also, we say that R is a phi-Bezout ring if phi(I) is a principal ideal of phi(R) for every finitely generated nonnil ideal I of R. We show that the theories of phi-Prüfer and phi-Bezout rings resemble that of Prüfer and Bezout domains.
		In a manner analogous to the commutative case, the zero-divisor graph of a noncommutative ring R can be defined as the directed graph G. It has been shown that G is not a tournament if R is a finite ring with no nontrivial nilpotent elements and the graph has more than one vertex.
		This article also shows that G cannot be a network for a finite ring R. These results are used to determine which directed graphs on 1, 2, or 3 vertices can be realized as G. Finally, it is shown that for a finite ring R, G has an even number of directed edges.

		One such trick is to get a ring dropped around the outside of a loop of string to become tied to that loop with a knot.
		While holding one end of the loop, grab the ring and slowly pull it in the opposite direction.
		If you hold the correct end and grab the ring in exactly the right place, you should be able to knot the ring to the string.

	Clyde Davenport's Commutative Hypercomplex Math Page (Site not responding. Last check: )
		What he didn't realize was that the quaternions form a group ring [i.e., the 1,i,j,k elements and their negatives form a group of order eight (the quaternion group, of course), and elements of the form 1x+iy+jz+kw, with x,y,z,w real, form a ring].
		The fact that we exclusively use the quaternion case (vector analysis) in science and engineering apparently stems from the fact that it was discovered first and the others were not examined for potential application when they were eventually uncovered.
		All of the other conditions for a ring are satisfied, as well; see [Davenport(3), 1991] for details.
