Examples

 * 1) The set of integers $$ \mathbb Z $$, the set of rationals $$ \mathbb Q $$, the set of reals $$ \mathbb R $$, the set of complex numbers $$\mathbb C$$ are all examples of commutative rings with identity. The sets $$\mathbb Q, \mathbb R$$ are division rings.
 * 2) Matrix Rings: The set Mn(R) which denotes the set of all $$n\times n $$ matrices with entries from ring R is called as a matrix ring with respect to usual addition and multiplication.
