Mathematical Structures and Commutativity
- A commutative semigroup is a set endowed with a total, associative and commutative operation.
- If the operation additionally has an identity element, we have a commutative monoid
- An abelian group, or commutative group is a group whose group operation is commutative.
- A commutative ring is a ring whose multiplication is commutative. (Addition in a ring is always commutative.)
- In a field both addition and multiplication are commutative.

Famous quotes containing the words mathematical and/or structures:
“An accurate charting of the American woman’s progress through history might look more like a corkscrew tilted slightly to one side, its loops inching closer to the line of freedom with the passage of time—but like a mathematical curve approaching infinity, never touching its goal. . . . Each time, the spiral turns her back just short of the finish line.”
—Susan Faludi (20th century)
“If there are people who feel that God wants them to change the structures of society, that is something between them and their God. We must serve him in whatever way we are called. I am called to help the individual; to love each poor person. Not to deal with institutions. I am in no position to judge.”
—Mother Teresa (b. 1910)
