## What is Algebra in Math

Algebra mainly focuses on variables, which have unknown values. These variables may change. Variables are symbols like x, y, z, p, or q.

Mathematical operations like addition, subtraction, multiplication, and division are combined with variables like x, y, and z to form a meaningful equation. It follows a set of laws when performing mathematical operations. When analyzing data sets with two or more variables, the rules are used.

## Algebra Definition

Algebra is a branch of mathematics that deals with symbols and the rules to solve equations and it focuses on operations with variables, constants, and mathematical expressions.

## Algebra Branches

The various branches of Algebra based on the use and complexity of the expressions are as such:

- Pre Algebra
- Elementary Algebra
- Abstract Algebra
- Universal Algebra
- Linear Algebra
- Commutative Algebra

### Pre Algebra

Pre Algebra includes the fundamental concepts of arithmetic and algebra, such as the order of operations, basic operations with numbers, and simplifying expressions.

Algebra assists in turning day-to-day problems into mathematical expressions that use algebraic techniques and algebraic expressions. Pre-algebra specifically involves creating an algebraic expression for the provided problem statement.

### Algebra 1 or Elementary Algebra

The goal of elementary Algebra is to find a solution by resolving Algebraic expressions. Simple variables like x and y are expressed as equations in elementary Algebra.

- The equations are divided into polynomials, quadratic equations, or linear equations depending on the degree of the variable.
- The formulas for linear equations are ax + b = c, ax+ by + c = 0, and ax + by + cz + d = 0.
- Based on the number of variables, quadratic equations, and polynomials are subsets of Elementary Algebra.
- For a polynomial problem, the typical form of representation is ax
^{n}+ bx^{n-1}+ cx^{n-2}+…..k = 0, while for a quadratic equation, it is ax^{2}+ bx + c = 0.

### Abstract Algebra

Abstract Algebra is a branch of mathematics that focuses on Algebraic systems like groups, rings, fields, and modules, rather than on specific numerical computations.

- In abstract Algebra, we do not study specific operations like addition and multiplication but instead study general properties of basic operations, such as associativity, commutativity, distributivity, and the existence of inverses.
- Groups, sets, modules, rings, lattices, vector spaces, and other Algebraic structures are studied in abstract Algebra.

### Universal Algebra

Universal Algebra can be used to explain all other mathematical forms using Algebraic expressions in coordinate geometry, calculus, and trigonometry. In each of these areas, universal Algebra focuses on equations rather than Algebraic models.

- You can think of all other types of Algebra as being a subset of universal Algebra.
- Any real-world issue can be categorized into a particular discipline of mathematics and solved using abstract Algebra.

### Linear Algebra

Linear algebra, a branch of algebra, finds uses in both pure and practical mathematics. It deals with the linear mappings of the vector spaces. It also involves learning about lines and planes. It is the study of linear systems of equations with transformational features.

- It is used in almost all areas of mathematics.
- It deals with the representation of linear equations for linear functions in matrices and vector spaces.

### Commutative Algebra

Commutative algebra is one of the types of algebra that studies commutative rings and their ideals. Both algebraic geometry and algebraic number theory require commutative algebra.

- Rings of algebraic integers, polynomial rings, and other rings are all present.
- Numerous other areas of mathematics, such as differential topology, invariant theory, order theory, and generic topology, make use of commutative algebra.

## Algebraic Expressions with Examples

** Algebraic Expressions consist of constants and variables.** We can add, subtract, multiply, and divide these expressions.

** An example of an algebraic expression is 5x + 6**. The variables might also have values like x

^{2}, x

^{3}, x

^{n}, xy, x

^{2}y, etc.

Polynomials is also a term used for algebraic expressions. An equation that contains coefficients, non-negative integer exponents of variables, and variables is called a polynomial. For example, 5x^{3} + 4x^{2} + 7x + 2 = 0.

## Algebraic Equations

An algebraic equation shows the connection between two quantities when one or both of the values are unknown.

Given below are the **different types of Algebraic equations, based on the degree of the variable:**

- Linear Equations
- Quadratic Equations
- Cubic Equations

**Linear Equation**

**Linear Equation**

A linear equation is an equation in which the highest power of a variable is 1. They are also known as first-order equations.

- A linear equation is an equation for a straight line when seen in the coordinate system.
- The straight-line equation is written as y = mx + b, where m denotes the line’s slope and b denotes the y-intercept.

### Quadratic Equation

A quadratic equation is a type of algebraic equation that contains one or more terms in which the variable is raised to the power of 2 (i.e., a quadratic term). It is an equation of the form ax

^{2}+ bx + c = 0, where a, b, and c are constants and x is the variable.

^{3}+ bx^{2}+ cx + d = 0.where x is a variable and a, b, c, and d are constants.

- A cubic equation can have one, two, or three solutions that are real or complex numbers, depending on the coefficients in the equation.

**Polynomial**

**Polynomial**

Polynomials are made by variables and coefficients, which are Algebraic expressions. Indeterminate is another name for variables. For polynomials, we can perform addition, subtraction, multiplication, and positive integer exponents, but not division by variable. For ex: 3x

^{3}-5x+8 .

### Sequence and Series

An ordered collection of numbers or other elements of mathematics that follow a pattern or rule is called a sequence.

- The position of each term of a sequence within the sequence is marked by its index or subscript.
- The series of even numbers, for example, can be written as 2, 4, 6, 8, 10, and so on.
- The total of a sequence’s terms forms a series.
- For instance, the series 2 + 4 + 6 +… + 2n gives the sum of the first n terms of the even number sequence.
- Series may be finite or infinite.
- Sequence and Series can be classified into two major categories – Arithmetic Progression and Geometric Progression.

### Arithmetic Progression

Arithmetic Progression(A.P) is a series of numbers where each term is obtained by adding a constant /fixed value to the previous term. This continuous difference in the terms is denoted by ‘d’.

The general format of an A.P is:

a, a + d, a + 2d, a + 3d, …, a + ndwhere

is the first term,ais a common difference, anddis the number of terms.n

### Geometric Progression

Geometric Progression(G.P) is a series of numbers where each term is obtained by multiplying the preceding term by a fixed constant value called the common ratio, denoted by r.

The general form of a geometric progression is:

a, ar, ar^{2}, ar^{3}, …, ar^{n}where

is the first term,ais the common ratio, andris the number of terms.n

### Exponents

Exponent is a mathematical operation, written as a^{n} where a is the base and n is the power or the exponent. Exponents help us simplify Algebraic expressions. Exponent can be represented in the form

a^{n }= a*a*a*….n times.

### Logarithms

The Algebraic opposite of exponents is the logarithm. It is practical to simplify complicated Algebraic formulas using logarithms. The exponential form denoted by the formula a

^{x}= n can be converted to logarithmic form by using the formula log_{a}n = x.

In 1614, John Napier discovered logarithms. Nowadays, logarithms are a crucial component of modern mathematics.

**Set Theory**

**Set Theory**

Set theory is a branch of mathematical logic that investigates sets, which are arrays of objects informally.

- The term “set” refers to a well-defined group of unique items that are used to express Algebraic variables.
- Sets are used to depict the collection of important elements in a group.
- Sets can be expressed in set-builder or roster form.
- Sets are usually denoted by curly braces;{} for example, A = {1,2,3,4} is a collection.

**Let’s learn more about the sets in the following articles:**

- Sets and their representations
- Different kinds of Sets
- Subsets, Power Sets, and Universal Sets
- Venn Diagrams

**Vectors**

**Vectors**

A vector is a two-dimensional object of both magnitude and direction. It is normally represented by an arrow with a length (→) that indicates the magnitude and direction. It is denoted by the letter V.

- One of the most important aspects of Algebra is vector Algebra.
- It is a course that focuses on the Algebra of vector quantities.
- As we all know, there are two kinds of measurable quantities: scalars and vectors.
- The magnitude of a scalar quantity is the only thing that matters, while the magnitude and direction of a vector quantity are also essential.
- The vector’s magnitude is denoted by the letter |V|.

**Let’s discuss the vector and its Algebra in the following articles:**

**Relations and Functions**

**Relations and Functions**

Relations and functions are two distinct terms that have different mathematical interpretations. One might be puzzled by the differences between them.

- Before we go even further, let’s look at a clear example of the differences between the two.
- An ordered pair is represented as (INPUT, OUTPUT): The relation shows the relationship between INPUT and OUTPUT. Whereas, a function is a relation that derives one OUTPUT for each given INPUT.

**Let’s discuss more of the topic in the following articles:**

- Relations and functions
- Types of Functions
- Composite functions
- Invertible Functions

- Range of a Function

**Matrices and Determinants**

**Matrices and Determinants**

In linear Algebra, determinants, and matrices are used to solve linear equations by applying Cramer’s law to a series of non-homogeneous linear equations.

- Only square matrices are used to measure determinants. While a matrix’s determinant is empty, it’s known as a singular determinant, and when its determinant is one, it’s known as unimodular.
- The determinant of the matrix must be nonsingular, that is, its value must be nonzero, for the set of equations to have a unique solution.

**Let us look at the definitions of determinants and matrices, as well as the various forms of matrices and their properties, using examples in the following articles:**

**Permutations and Combinations**

Permutation and Combination are methods for representing a collection of objects by choosing them from a list and dividing them into subsets.

- It specifies the different methods for organizing a set of data.
- Permutations are used to choose data or events from a group, while combinations are used to represent the order in which they are represented.

## Exponential & logarithmic functions

**Exponential Function Definition**

**Exponential Function Definition**

An exponential function is a mathematical function in the form

y=f(x)=bx

where “x” is a variable and “b” is a constant which is called the base of the function such that

b>1

The most commonly used exponential function base is the transcendental number e, and the value of e is approximately 2.71828.

**Logarithmic Function Definition**

**Logarithmic Function Definition**

If the inverse of the exponential function exists then we can represent the logarithmic function as given below: Suppose

b>1

is a real number such that the logarithm of a to base b is x if

b^{x}=a

The logarithm of a to base b can be written as

log_{b}a

Thus,

log_{b}a=x

if

b^{x}=a

In other words, mathematically, by making a base

b>1

we may recognize logarithm as a function from positive real numbers to all real numbers.

**Properties of Exponential and Logarithmic Functions**

**Properties of Exponential and Logarithmic Functions**

- The domain of the exponential function is the set of all real numbers, i.e. R.
- The range of the exponential function is the set of all positive real numbers.
- The point (0, 1) is always on the graph of the given exponential function since it supports the fact that b
^{0}=1 for any real number b>1 . - The exponential function is ever increasing; i.e., as we move from left to right, the graph rises above.
- The domain of the log function is the set of positive real numbers, i.e. R+.
- The range of the log function is the set of all real numbers.
- The point (1, 0) is always on the graph of the log function.

Exponential and logarithmic functions are related to each other since the inverse of exponential functions are the basis for defining logarithmic functions.

## Algebra Formula

Here are some important algebraic formulas:

- a
^{2}−b^{2}=(a−b)(a+b) - (a+b)
^{2}=a^{2}+2ab+b^{2} - a
^{2}+b^{2}=(a+b)^{2}−2ab - (a−b)
^{2}=a^{2}−2ab+b^{2} - (a+b+c)
^{2}=a^{2}+b^{2}+c^{2}+2ab+2bc+2ca - (a−b−c)
^{2}=a^{2}+b^{2}+c^{2}−2ab+2bc−2ca - a
^{3}−b^{3}=(a−b)(a2+ab+b2) - a
^{3}+b^{3}=(a+b)(a2−ab+b2) - (a+b)
^{3}=a^{3}+3a^{2}b+3ab^{2}+b^{3} - (a−b)
^{3}=a^{3}−3a^{2}b+3ab^{2}−b^{3} - a
^{4}−b^{4}=(a−b)(a+b)(a^{2}+b^{2}) - a
^{5}−b^{5}=(a−b)(a^{4}+a^{3}b+a^{2}b^{2}+ab^{3}+b^{4})

If “n” is a natural number:

- a
^{n}−b^{n}=(a−b)(a^{n−1}+a^{n−2}b+…+b^{n−2}a+b^{n−1}) - If “n” is even (n = 2k), a
^{n}+b^{n}=(a+b)(a^{n−1}−a^{n−2}b+…+b^{n−2}a−b^{n−1}) - If “n” is odd (n = 2k + 1), a
^{n}+b^{n}=(a+b)(a^{n−1}−a^{n−2}b+…−b^{n−2}a+b^{n−1})

## Algebraic Operations

There are four basic mathematical operations that are used in Algebra. These are addition, subtraction, multiplication, and Division. These are discussed below:

### Algebraic** Addition**

**Addition**

The summation of two or more algebraic terms is done in Addition. The addition of algebraic terms is indicated by “+” symbol.

- The addition of algebraic terms to yield a single value is only possible if there are like algebraic terms else the expression remains as it is.
- For Example, 3x
^{2}y + 5x^{2}y = 8x^{2}y as 3x^{2}y and 5x^{2}y are like algebraic terms while if we add 3xy^{2}and 5x^{2}y then it will not yield a single value instead it will remain as it is i.e. 3xy^{2}+ 5x^{2}y.

### Algebraic** Subtraction**

**Subtraction**

The method of finding the difference between two algebraic terms is called Subtraction of Algebraic terms. Subtraction of algebraic terms is indicated by “-” terms.

- Like Addition, Subtraction is also possible only between the like algebraic terms.
- For example, if we subtract 3x
^{2}y from 5x^{2}y it will give a difference as 5x^{2}y – 3x^{2}y = 2x^{2}y. - But if subtract 3xy
^{2}from 5x^{2}y it will not yield a single value as the two terms are unlike. Hence, the difference will be written as 5x^{2}y – 3xy^{2}.

### Algebraic** Multiplication **

**Multiplication**

Unlike Addition and Subtraction, Multiplication is possible between both like and unlike terms. Multiplication of algebraic terms is indicated by “⨯” or (a)(b).

- While performing the multiplication of algebraic terms, multiply the numerical coefficient as normal numbers and multiply the variables using the laws of exponents.
- For Example, if we multiply 4x
^{2}y with 5xyz then the product is given as (4x^{2}y)(5xyz) = 20x^{3}y^{2}z.

### Algebraic** Division**

**Division**

Like Multiplication, Division of algebraic terms is possible between both like and unlike terms while keeping in mind the laws of exponents for variables and normal division for numbers.

- The division between algebraic terms is indicated by the “/” symbol. For Example, the division of 6x
^{2}y^{2}by 3xy^{2}is given as 6x^{2}y^{2}/3xy^{2}= 2x.

## Algebraic Laws

** Algebraic Laws or Properties include Closure, Commutative, Associative, Distributive, and Identity Properties**. These properties are defined for basic algebraic operations such as Addition, Subtraction, Multiplication, and Division.

A picture explaining algebraic laws has been attached below:

## Algebraic Identities

Algebraic Identities are the expansion of terms of algebraic terms given as whole square or whole cube generally. These expansions help us to quickly solve the problems.

Some of the commonly used algebraic identities are mentioned below:

- (a + b)
^{2}= a^{2}+ 2ab +b^{2} - (a – b)
^{2}= a^{2}– 2ab + b^{2} - a
^{2}– b^{2}= (a + b)(a – b) - (a + b)
^{3}= a^{3}+ b^{3}+ 3a^{2}b + 3ab^{2} - (a – b)
^{3}= a^{3}– b^{3}– 3a^{2}b + 3ab^{2}

## Algebra Solved Examples

Here we have provided some solved examples on algebra for your better understanding.

**Algebra Example 1: Solve 3e**^{x}** + 6 = 120**

**Algebra Example 1: Solve 3e**

^{x}

**+ 6 = 120**

**Solution:**

Given,

3e

^{x}+ 6 = 1203e

^{x}= 120 – 63e

^{x}= 114e

^{x}= 114/3e

^{x}= 38x = ln 38

**Algebra Example 2: Solve for the value of y: 2(4-y)-3(y+3)=11**

**Algebra Example 2: Solve for the value of y: 2(4-y)-3(y+3)=11**

**Solution:**

2(4-y) -3(y+3)=11

8-2y-3y-9=11

-5y-1=-11

-5y-1+1=-11+1

-5y=-10

Dividing both the sides by -5,

-5y/-5=-10/-5

y=2

**Algebra Example 3: Evaluate (2.3a**^{5}**b**^{2}**) × (1.2a**^{2}**b**^{2}**) when a = 1 and b = 0.5**

**Algebra Example 3: Evaluate (2.3a**

^{5}

**b**

^{2}

**) × (1.2a**

^{2}

**b**

^{2}

**) when a = 1 and b = 0.5**

**Solution:**

Let us simplify the given expression

=2.3a

^{5}b^{2}× 1.2a^{2}b^{2}=2.3 × 1.2 × a

^{5}× a^{2}× b^{2}× b^{2}=2.76 × a

^{5+2}× b^{2+2}=2.76a

^{7}b^{4}Now let us substitute when, a = 1 and b = 0.5

For 2.76 a

^{7}b^{4}=2.76 (1)

^{7}(0.5)^{4}=2.76 × 1 × 0.0025

=0.1725

=6.9/40

**Algebra Example 4: (2x-1)/3 – (6x-2)/5 = 1/3**

**Algebra Example 4: (2x-1)/3 – (6x-2)/5 = 1/3**

**Solution:**

We have,

(2x-1)/3 – (6x-2)/5 = 1/3

By taking LCM for 3 and 5, which is 15

((2x-1)×5)/15 – ((6x-2)×3)/15 = 1/3

(10x – 5)/15 – (18x – 6)/15 = 1/3

(10x – 5 – 18x + 6)/15 = 1/3

(-8x + 1)/15 = 1/3

By using cross-multiplication, we get,

(-8x + 1)3 = 15

-24x + 3 = 15

-24x = 15 – 3

-24x = 12

x = -12/24

= -1/2

∴ x = -1/2

Verification

LHS = (2x – 1)/3 – (6x – 2)/5

= [2(-1/2) – 1]/3 – [6(-1/2) – 2]/5

= (- 1 – 1)/3 – (-3 – 2)/5

= – 2/3 – (-5/5)

= -2/3 + 1

= (-2 + 3)/3

= 1/3

RHS

**Algebra Example 5: Find a number such that when 5 is subtracted from 5 times that number, the result is 4, more than twice the number.**

**Algebra Example 5: Find a number such that when 5 is subtracted from 5 times that number, the result is 4, more than twice the number.**

**Solution:**

Let us consider the number as ‘x’

Then, five times the number will be 5x

And, two times, the number will be 2x

So,

5x – 5 = 2x + 4

5x – 2x = 5 + 4

3x = 9

x = 9/3

x = 3

∴ The number is 3.
