Algebra is a subpart of mathematics that deals with relations, operations, and their constructions. It is one of the building blocks of mathematics, and it finds a huge variety of applications in our day-to-day life.

Algebra is one of the many various branches of Mathematics. It deals with the binary relations, operations and constructions of various mathematical functions. Algebra is an integral part of a student’s education. It helps in developing the over all understanding of other Math branches. The other branches of Math include Calculus, Arithmetic, and Geometry etc.

The word Algebra is taken from the Arabic phrase al-jebr which means "reunion of broken parts". It is the study of multiple operations and relations, various constructions of geometric figures and the explanation and proofs of concepts such as polynomials, equations, and algebraic structures.

Now, the question arises, how is Algebra different from the other branches in Math? The answer to this is the Algebraic Expressions used in Algebra.

**What is an Algebraic Expression? **

**3x**^{2}** + 2y + 7xy + 5**

In this article, we will mainly focus on the definition and properties of constants and variables.

Algebraic expressions can be monomial, binomial and polynomial. Given below are the definitions of the three types.

**Monomial Expression **

7xy is an example of a monomial Expression.

**Binomial Expression **

4x+6 is an example of a binomial expression.

**Polynomial Expression **

ax+3y+6c=0 is an example of a polynomial expression.

There are two types of Expressions; they are** Numeric Expressions and Variable Expressions.**

For example,

2. Variable Expressions contain both variables and numbers to define a particular expression.

For example,

5x+y, 5ac-44 etc.

**What are Constants?**

**What are Variables? **

**The entire article in a nutshell **

What does ‘x’ and ‘y’ represent? They are quantities that can be continuously varied and can be substituted with different values. Hence, it is called a variable. It is usually an English alphabet that represents these values. A variable is a letter that signifies an unidentified. It always serves a number, but it carries varying values when written in the expression. In this expression x and y are variables. All algebraic expressions and terms consist of a minimum of one variable. It is this variable that distinguishes an algebraic expression from an arithmetic one. The variable in a mathematical expression can explain infinite possibilities to determine the value of the expression.

The constants over here are 4, 2 and 12. These values cannot be changed and represent a fixed mathematical expression at all times. Under no circumstances can the values be assumed differently or written differently.

Algebraic Expressions having one term is known as a monomial.

7xy is an example of a monomial Expression.

4x+6 is an example of a binomial expression.

ax+3y+6c=0 is an example of a polynomial expression.

There are two types of Expressions; they are

For example,

10-2, 3*4 etc.
