Etiam pulvinar consectetur dolor sed malesuada. Ut convallis euismod dolor nec pretium. Nunc ut tristique massa.

Nam sodales mi vitae dolor ullamcorper et vulputate enim accumsan. Morbi orci magna, tincidunt vitae molestie nec, molestie at mi. Nulla nulla lorem, suscipit in posuere in, interdum non magna.

Square numbers easily

 

Square numbers

You can square the numbers ending with 5 very easily using this Vedic math’s rule. For example you can calculate 352 as 35 x 35 or you can use the following rule to calculate in your mind.

Update: We have now included a small quiz on this concept : Click here

The concept is as follows:

  1. The last 2 digit would always be 25.
  2. Now  add 1 to the first numeral  and multiply it with the original numeral in our example this would be (3+1=4)x3=12.
  3. Now the result is 1225.

The rule can be generalized as for square of n2 results can shown as (n+1) x n 25
