ANSWER:
Step 1 of 3
A ring R is a set with two binary operations, addition and multiplication, satisfying several properties: R is an Abelian group under addition, and the multiplication operation satisfies the associative law
And distributive laws
And
For every
The identity of the addition operation is denoted 0. If the multiplication operation has an identity, it is called a unity. If multiplication is commutative, we say that R is commutative. Let A be a subring of a ring R. If, for every and
And
We say that A is an ideal of R.
If A is an ideal of R, the set of cosets under addition.
Is itself a ring. Addition is defined as
This ring is called the factor ring and denoted.
The ring of Gaussian integers is defined as
Under ordinary addition and multiplication of complex numbers. If a is an element of a commutative ring R with unity, the principal ideal generated by a is
