		In mathematics, the idea of inverse element generalises the concepts of negation, in relation to addition, and reciprocal, in relation to multiplication.
		If e is an identity element of (S, ) and a b = e, then a is called a left inverse of b and b is called a right inverse of a.
		If an element x is both a left inverse and a right inverse of y, then x is called a two-sided inverse, or simply an inverse, of y.

		Identity element: There is an element e in G such that for all a in G, e * a = a = a * e.
		Inverse element: For all a in G, there is an element b in G such that a * b = e = b * a, where e is the identity element from the previous axiom.
		You can perform division in groups; that is, given elements a and b of the group G, there is exactly one solution x in G to the equation x * a = b and exactly one solution y in G to the equation a * y = b.

		Incidentally, your subject line suggests that you are confusing the concept of inverse in a semigroup with that of an inverse operation, such as the logarithm.
		You are evidently looking for an explanation of inverse functions (and the logarithm in particular) in terms of inverse elements of a semigroup.
		I was curious why exponentiation and logarithm didn't seem to fit the general definition of inverses for semigroups, which you cleared up for me. I didn't know about some of the interplay between multiplicative inverses in the exponents and the operations of logarithm and exponentiation that you pointed out.

	ABSTRACT ALGEBRA: OnLine Study Guide, Section 3.1
		Loosely, a group is a set on which it is possible to define a binary operation that is associative, has an identity element, and has inverses for each of its elements.
		This still works for the operation in a group, since if x and y are elements of a group G, and x = y, then a ·: x = a · y, for any element a in G. This is a part of the guarantee that comes with the definition of a binary operation.
		The previous exercise shows that in the definition of a group it is sufficient to require the existence of a left identity element and the existence of left inverses.
