+		Haskellers are usually familiar with monoids and semigroups. A monoid has an appending operation `&lt;&gt;` (or `mappend`),
+		and an identity element, `mempty`. A semigroup has an appending `&lt;&gt;` operation, but does not require a `mempty` element.
+		
+		A Semiring has two appending operations, `plus` and `times`, and two respective identity elements, `zero` and `one`.
+		
+		More formally, a Semiring R is a set equipped with two binary relations `+` and `*`, such that:
+		
+		(R,+) is a commutative monoid with identity element 0,
+		
+		(R,*) is a monoid with identity element 1,
+		
+		(*) left and right distributes over addition, and
+		
+		multiplication by &#39;0&#39; annihilates R.
