What is Commutative ring?
In [[algebra]], '''commutative ring''' is a set of elements in which you can add and multiply and have [[multiplication]] distribute over [[addition]]. An example of a commutative ring is the set of [[integer]]s. If we add two integers, we get an integer and if we multiply two integers we get another integer. Moreover, multiplication distributes in the sense that if ''a'', ''b'', and ''c'' are integers, then ''c*(a+b)=ca+cb''. {{math-stub}} [[Category:Abstract algebra]]
