Addition is one of the four basic operations of arithmetic (the others being subtraction, multiplication, and division). In arithmetic, addition operates on the set of real numbers such that for any real numbers added together, another real number is...

In mathematics, an abelian group, also called a commutative group, is a group (G, * ) with the additional property that the group operation * is commutative, so that for all a and b in G, a * b = b * a. Abelian groups are named after Norwegian...

Abstract. -- Subtraction has always been considered secondary to the fundamental and primary operation of addition, in some measure because addition is associative while subtraction is not. This note shows how to obtain an abelian group with an addition like operation (Joyner 2002:70-72)...
