In ring theory, a branch of abstract algebra, an ideal is a special subset of a ring. Ideals generalize certain subsets of the integers, such as the even numbers or the multiples of 3. Addition and subtraction of even numbers preserves evenness, and multiplying an even number by any other integer results in another even number; these closure and absorption properties are the defining properties of an ideal. An ideal can be used to construct a quotient ring similarly to the way that, in group theory, a normal subgroup can be used to construct a quotient group.
Among the integers, the ideals correspond one-for-one with the non-negative integers: in this ring, every ideal is a principal ideal consisting of the multiples of a single non-negative number. However, in other rings, the ideals may be distinct from the ring elements, and certain properties of integers, when generalized to rings, attach more naturally to the ideals than to the elements of the ring. For instance, the prime ideals of a ring are analogous to prime numbers, and the Chinese remainder theorem can be generalized to ideals. There is a version of unique prime factorization for the ideals of a Dedekind domain (a type of ring important in number theory).
In algebra, which is a broad division of mathematics, abstract algebra (occasionally called modern algebra) is the study of algebraic structures. Algebraic structures include groups, rings, fields, modules, vector spaces, lattices, and algebras. The term abstract algebra was coined in the early 20th century to distinguish this area of study from the other parts of algebra.
Universal algebra is a related subject that studies the nature and theories of various types of algebraic structures as a whole. For example, universal algebra studies the overall theory of groups, as distinguished from studying particular groups.
History
As in other parts of mathematics, concrete problems and examples have played important roles in the development of abstract algebra. Through the end of the nineteenth century, many -- perhaps most -- of these problems were in some way related to the theory of algebraic equations. Major themes include:
An ideal of a ring is the similar to a normal subgroup of a group. Using an ideal, you can partition a ring into cosets, and these cosets form a new ring - a "factor ring." (Also called a "quotient ring.")
After reviewing normal subgroups, we will show you *why* the definition of an ideal is the simplest one that allows you to create factor rings.
As an example, we will look at an ideal of the ring Z[x], the ring of polynomials with integer coefficients.

Ideals, Ideal Test, Principal Ideals vs Cyclic Subgroups, Factor (Quotient) Ring Example
In a Ring R from Abstract Algebra, a two-sided ideal is a subring A that is "absorbing" or "super-closed" under multiplication of elements in R that are not in A. In a commutative ring, the principal ideal generated by an element "a" is the set of all ring-multiples of the element. This has significant applications for equation-solving in polynomial rings. How are principal ideals different than cyclic subgroups?

Maximal and Prime Ideal of Z27
First we find all the subgroups of Z27 ,,
z27 ={0,1,2,.......26}
The subgroups are those sets which are generated by each elements
cyclic generator is a element in z27 which covers all elements note these generators is neither maximal nor prime ideal here are those cyclic generators 1,2,4,5,... and all those elements which are relatively prime with 27
the remaining ideals are only generated by 3 and 9
but 9 is completely lies in 3
hence We conclude that MAXIMAL OF Z27 is 3={0,3,6,9,12,15,18,21,24}
And Every Maximal is Prime Ideal
So therefore Prime Ideal of Z27 is only 3 .
But someone say that why 9 is not a Prime Ideal
The 9 is not a prime Ideal because
As 9= {0,9,18}, By the definition of prime ideal
as 3.6 = 18 but neither 3 nor 6 belongs to 9
hence 9 is not a Prime ideal of Z27

An ideal of a ring is the similar to a normal subgroup of a group. Using an ideal, you can partition a ring into cosets, and these cosets form a new ring - a "factor ring." (Also called a "quotient ring.")
After reviewing normal subgroups, we will show you *why* the definition of an ideal is the simplest one that allows you to create factor rings.
As an example, we will look at an ideal of the ring Z[x], the ring of polynomials with integer coefficients.

This lecture is part of an online course on rings and modules.
We discuss prime and maximal ideals of a (commutative) ring, use them to construct the spectrum of a ring, and give a few examples.

Proof of every Maximal is prime ideal of Commutative Ring R with unity
https://youtu.be/xwv_CX_RDzY
for more examples:- https://youtu.be/ykk4tapokxw
Proof by using definition
Every Maximal ideal is prime ideal proof :-. https://youtu.be/XpZp7OtoYCQ
Maximal and Prime Ideal of Z27
First we find all the subgroups of Z27 ,,
z27 ={0,1,2,.......26}
The subgroups are those sets which are generated by each elements
cyclic generator is a element in z27 which covers all elements note these generators is neither maximal nor prime ideal here are those cyclic generators 1,2,4,5,... and all those elements which are relatively prime with 27
the remaining ideals are only generated by 3 and 9
but 9 is completely lies in 3
hence We conclude that MAXIMAL OF Z27 is 3={0,3,6,9,12,15,18,21,24}
And Every Maximal is Prime Ideal
So therefore Prime Ideal of Z27 is only 3 .
But someone say that why 9 is not a Prime Ideal
The 9 is not a prime Ideal because
As 9= {0,9,18}, By the definition of prime ideal
as 3.6 = 18 but neither 3 nor 6 belongs to 9
hence 9 is not a Prime ideal of Z27

In a Ring R from Abstract Algebra, a two-sided ideal is a subring A that is "absorbing" or "super-closed" under multiplication of elements in R that are not in A. In a commutative ring, the principal ideal generated by an element "a" is the set of all ring-multiples of the element. This has significant applications for equation-solving in polynomial rings. How are principal ideals different than cyclic subgroups? What is the nature of the finite field ℤ3[x]/(x^2+1), which is a factor ring defined by modding by the principal ideal generated by an irreducible polynomial over ℤ3? 🔴 "Contemporary Abstract Algebra", by Joe Gallian: https://amzn.to/2ZqLc1J

In ring theory, a branch of abstract algebra, an ideal is a special subset of a ring. Ideals generalize certain subsets of the integers, such as the even numbers or the multiples of 3. Addition and subtraction of even numbers preserves evenness, and multiplying an even number by any other integer results in another even number; these closure and absorption properties are the defining properties of an ideal. An ideal can be used to construct a quotient ring similarly to the way that, in group theory, a normal subgroup can be used to construct a quotient group.
Among the integers, the ideals correspond one-for-one with the non-negative integers: in this ring, every ideal is a principal ideal consisting of the multiples of a single non-negative number. However, in other rings, the ideals may be distinct from the ring elements, and certain properties of integers, when generalized to rings, attach more naturally to the ideals than to the elements of the ring. For instance, the prime ideals of a ring are analogous to prime numbers, and the Chinese remainder theorem can be generalized to ideals. There is a version of unique prime factorization for the ideals of a Dedekind domain (a type of ring important in number theory).
