Finding Square of an adjacent number: One up PDF Print E-mail

You know the squares of 30, 40, 50, 60 etc. but if you are required to calculate square of 31 or say 61 then you will scribble on paper and try to answer the question. Can it be done mentally? Some of you will say may be and some of you will say may not be. But if I give you a formula then all of you will say, yes! it can be. What is that formula…..

The formula is simple and the application is simpler.

Say you know 602 = 3600

Then 612 will be given by the following

612 = 602 + (60 + 61) = 3600 + 121 = 3721

or Say you know 252 = 625 then

262 = 625 + (25 + 26) = 676

Like above, you can find out square of a number that is one less than the number whose square is known. In this I have utilized the Base Technique of Vedic Maths. You can use this technique to find the square of a number which is one more than the square of a known number.
