  Finding squares is very easy   Awaiting Review for Nickels
Tagged with:    [Post New]posted on 28 Jan 2008 20:14:31 IST    
Hi friends it seems that no one knows easy method to find squares as no one has submitted articles on it.
Please try this method and if you like this then please rate me.
The method is as follows:
 
Take a number other than 1 of which square is to be found out.
Take one number less than it and one number more than it.
Now multiply these.
Now add 1 to the product.
The output is the square of the required number.
 
Example:
To find a square of 19.
Multiply 18 and 20.
The product is 360.
Now add 1 to this product.
The output is 361.
Therefore the square of 19 is 361.
 
This is known as N's formula means Navin's formula.

its based on the formula n^2 -1 = (n+1)(n-1) .

But i dont understand what's the trick here because instead of multiplying 38*38 , we have to now multiply 37*39 . what 's the advantage here?

Hey nadeemoidu,
The difference in these fomulas is that u have to add one. Try again and do comment me for my satisfaction.

n^2 -1 = (n+1)(n-1)
n^2 = (n+1)(n-1) + 1

but i am asking is that , what 's the use of this. if u multiply 37 by 39 and add 1 instead of multiplying 38 by 38 , is there any advantage?

GREAT WORK MAN!!!!!!!!!!!!!!!!!!!!!!!!!!!! REALLY USEFUL.......... :) :) :) :) :)

@nadeemoidu,
Advantage is in finding the square of no.,s like 49 , 59 etc. 49*49 will take more time than 48*50+1.......... :) :) :) :) :)

its Nice....
BUT for multiplying the numbers 1 less and 1greater we can directly multiply the number twice...

eg:

to find the square of 19

multiply 19 x 19 = 361....

this is more simpler.... ANY WAY THANK U
