Learn basic maths for class 10

Before going to in class10 you must have to know some basic formulas and identities that help you in understanding the chapters of class 10  maths as well as the physics portion of class10 science.

So as a student you must have a clear about maths subject that it is not learning subject it is known as a practice subject. So to understand maths you have to know even identities and formulas must be on your lips, whatever and however you did in class9 but before starting maths of class10 you have to read important without skipping any line.

So let's start,

1. Basic addition, subtraction, multiplication, and division if you know then come to the next point otherwise please know how to add, subtract, multiply and divide if the question is given in fractions form.

Understand with examples;

Que.1 add 1/2 and 1/3?

Ans.   =1/2+1/3

         

t do this you know the basic formula that is 

c=1/a+1/b is given then,

  

=3+2/2*3

=5/6

c=b+a/ab   keep in your mind a very important formula if you don't know or you are seeing the first time.

Que2subtract 1/2 and 1/3?

Ans.  =1/2-1/3

 

c=1/a-1/b

   =b-a/a*b

=3-2/6

=1/6

Que.3 1/2*1/3

Ans. =1/2*1/3

c=1/a*1/b

c=1/a*b

=1/6

Que4. divide the numbers 1/2 and 1/3?

Ans. =(1/2) /(1/3)

=1/2* 3/1

=3/2

I hope you have understood the above explanation because it is used in mirror and lens formula also in physics 9scince) in class10.

2.Now Learn basic identities that is written below

1. (a+b)^2=a^2+b^2+2ab

2.(a-b)^2=a^2+(-b)^2+2a(-b)

               =a^2+b^2-2ab

3.(a-b)*(a-b)=a^2-b^2
