Mathematics

The abstract science of number, quantity, and space, either as abstract concepts ( pure mathematics ), or as applied to other disciplines such as physics and engineering.

"Mathematics is a magics  game. 

We can learn mathematics with play.

 It is very easy to understand."

let's solve  the problem with play..........

Addition

Addition is the mathematical process of putting things together. The plus sign "+"means that numbers are added together. ... Repeated addition of 1 is the same as counting; addition of 0 does not change a number. Addition also obeys predictable rules concerning related operations such as subtraction and multiplication.

Subtraction

Subtraction in mathematics means you are taking something away from a group or number of things. When you subtract, what is left in the group becomes less. An example of a subtraction problem is the following: 5 - 3 = 2.

Multiplication

The basic idea of multiplication is repeated addition.

         
            1)                           12                                   

            *  35       

          420


2)

3)

4)                   4*3=12

 Division

In mathematics, the word "division" means the operation which is the opposite of multiplication.

  

          1)     245÷5=49

                2)   3/4÷2/6

           

         soln: =3/4÷2/6

                     =3/4×6/2

                     =9/2

  

               3)       27  
                           3    
            soln:=9
