Value of an Algebraic Expression

Before we learn How to Find the Value of an Algebraic Expression, you must know
What are Contants and Literal Numbers.(these topics are also available in the site)

Value of an Algebraic Expression :-
By assigning values to literal numbers in an algebraic expression, you can find the value of the expression.

From following examples you can learn How to Find The Value of an Algebaic Expression:-

Example 1 = Find the value of algebraic expression p+q+r, if p=1, q=2, r=3
Answer = Here, the given algebraic expression is p+q+r.
Put the respective values of literal numbers p,q, r in the algebraic expression, and we get
=1+2+3
=6
So The Value of the Given Algebraic Expression p+q+r is 6.

Example 2 = Find the value of algebraic expression 7x-3y+4, if x=2,y=3
Answer = Here, the given algebraic expression is 7x-3y+4
Put the respective values of literal numbers x and y in the algebraic expression, and we get
=7*2-3*3+4
=14-9+4
=14+4-9
=18-9
=9
=9
So The Value of the Given Algebraic Expression 7x-3y+4 is 9.

Example 3 = Find the value of algebraic expression 8a/4b, if a=2,b=2
Answer = Here, the given algebraic expression is 8a/4b
Put the respective values of literal numbers a and b in the algebraic expression, and we get
=8*2/4*2
=16/8
=2
So The Value of the Given Algebraic Expression 8a/4b is 2.
