What is an Algebraic Expression?
Algebraic Expression Definition:Â An algebraic expression in mathematics is an expression which is made up of variables and constants along with algebraic operations (addition, subtraction, etc.) Expressions are made up of terms.
Example of algebraic expression:
3x+4y 7, Â 4x – 10 etc.
It is to be noted that, unlike algebraic equation, an algebraic expression has no sides or equal to sign. Some of its examples include
 3x+4y 7
 4x – 10
 2x^{2}âˆ’3xy+5
The terminology used in Algebraic expressions:
In Algebra we work with Variable, Symbols or Letters whose value is unknown to us.
In the above expression (i.e. 5x – 3),
 x is a Variable, whose value is unknown to us which can take any value.
 5 is known as the Coefficient of x, as it is a constant value used with the variable term and is well defined.
 3 is the Constant value term which has a definite value.
The whole expression is known to be the Binomial term, as it has two unlikely terms.
Types of Algebraic expression:
There are 3 mains types of algebraic expressions which include:
 Monomial Expression
 Binomial Expression
 Polynomial Expression
Monomial Expression
An algebraic expression which is having only one term is known as a monomial.
Examples of monomial expression include 3x^{4}, 3xy, etc.
Binomial Expression
A binomial expression is an algebraic expression which is having two unlikely terms.
Examples of binomial include 5xy + 8, xyz + x^{3}, etc.
Polynomial Expression
In general, an expression with more than one terms with nonnegative integral exponents of a variable is known as aÂ polynomial.
Examples of polynomial expression includeÂ abÂ +Â bcÂ +Â ca,Â Â etc.
Other Types of Expression:
Apart from monomial, binomial and polynomial types of expressions, alebraic expression can also be classsified into two additional types which are:
 Numeric Expression
 Variable Expression
Numeric Expression:
A numeric expression consists of numbers and operations, but never include any variable. Some of the examples of numeric expressions areÂ 10+5, 15Ã·2, etc.
Variable Expression:
A variable expression is an expression which contains variables along with numbers and operation to define an expression. A few examples of a variable expression includeÂ 4x+y, 5ab + 33, etc.
Algebraic Expression Example Question
