‘Math’ always gave me extra nerve ever since I can remember. It was possibly the only subject that caught my interest early in life.
I remember having learnt Vedic Mathematics during my high-school days. But, to the credit of my memory, I barely find any remains. It’s been a while that I have been thinking to brush up those tricks…and the way I thought I could share is to blog! So, here I go…
Starting with something really basic, I would like to write on how to find the squares of numbers ending with ‘9’.
Add 1 to the number whose square you want to find.
For e.g. let’s suppose your number is 59. Add 1 to it. 59 + 1 = 60.
Add the two numbers. 59 + 60 = 119 …. Result (1)
Find the square of the number you got by adding 1 to your original number.
60^2 = 3600 ….Result (2)
(Pretty straightforward, as 6^2 = 36, append two zeros to your answer)
Subtract Result (1) from Result (2)
i.e. 3600 – 119 = 3481.
Yippee..that’s your answer! Kind of neat and simple. It needs to be constantly used, to avoid yourself from forgetting it!
Cheers till then,
