  As you probably know “An Algebraic identity is an algebraic equation that is true for all values of the variables occurring in it.” These Identities play a vital role in any algebraic or mathematical calculation. So, this post is made for the short revision of the Algebraic Identities. Some of these are : ·         ( x + y ) 2 = x 2 + 2 xy + y 2 ·         ( x - y ) 2 = x 2 - 2 xy + y 2 ·         x 2 – y 2 = ( x + y ) ( x – y ) ·         ( x + a ) ( x + b ) = x 2 + ( a + b ) x + ab ·         ( x + y + z ) 2 = x 2  +  y 2  +  z 2 + 2( xy  +  yz  +  zx) ·         ( x + y ) 3 = x 3 + y 3 + 3 xy ( x + y )  ·         ( x – y ) 3 = x 3 – y 3 – 3 xy ( x – y ) ·  ...

 Numbers are the basic terms to embark upon any counting. Can we make any calculation without the help of any number ? Moreover, can you even count your fingers without using any number ? The answer is , No. In this post we are going to learn about what the numbers really are and how could be classified on the basis of their properties.   Can you answer the question  "What is a number ?" The answer is  " A number is an arithmetic value that represents a particular quantity. It is expressed by symbols, words and figures. It is used in counting and making calculations."   It probably looks like a theoretical note but, it is the explanation of a number.   Now we are moving towards Types of Numbers. Natural Numbers  -  Numbers that are naturally used in counting are called natural numbers. They are denoted by N. These are ; (1,2,3,…so on.) Whole numbers –  If o is also considered as a number then natural numbers and 0 together made set of nu...
