Vedic Math: Crunch more in less time!

SHRADDHA KAMDAR | Wednesday, October 15, 2003 12:6:50 IST

Thousand-year-old 'sutras' can put the modern math methods to shame

Scientific techniques developed thousands of years ago, mentioned in

the Vedas, are now being utilised by America's National Aeronautic &

Space Administration (NASA) and form a part of the curriculum in

European schools.

Sadly, however, they have lost importance in the country of origin.

Vedic Math, as it is called, is extracted from 16 'sutras' and 13

sub-'sutras' of the Vedas. It is a set of techniques, which can be

applied to a wide spectrum of mathematic topics, to reduce the

calculation time to one-tenth

of the actual time of any traditional method.

Professor Atul Gupta, an IIT engineer who chanced upon a book on

Vedic Math about a decade ago, was intrigued by it and learnt from

it. The process was long, but nonetheless interesting and fruitful.

Later, he thought of sharing his knowledge. Prof Gupta now has

school students, IIT aspirants, housewives and retired persons who

are simply math enthusiasts learning from him. "It is so

fascinating, it has turned math-haters into math-lovers," claimed

the professor.

Useful for Arithmetic, Algebra, Calculus, Trigonometry and

Astromomy, the techniques are easy to learn and remember. The

professor had this reporter so awe-struck with the methods, that it

was difficult to wind up the interview and move out of his class.

And he had not even touched the tip of the ice-berg. "Now you can

imagine what a treasure this is. It should be passed on to our

future generations," said Prof. Gupta. In that regard, he has

already conducted several workshops with school children.

"These techniques are very helpful for IIT aspirants, as the

entrance exam papers are full of such questions. If they save even

about 10 minutes over all, imagine how many more questions they'd be

able to attempt!" said Prof. Gupta for whom clearly Vedic Math is

not just something he teaches, but is also a passion.

How long does it take to divide 257910 by 9?

Using a Vedic Math technique, the answer can be arrived at in a

couple of seconds! How?

It's simple.

Add all the digits of the number 257910 and reduce it to a single

digit: 2+5+7+9+1+0=24. Reduce 24 further -- 2+4=6, which is the

remainder.

Another way is by removing the digit 9 while adding. Or even the

digits that add up to 9. For example, in 257910 don't use 9, 2 and

7. By adding the remaining digits, you still get the correct answer,

i.e. 5+1+0=6.

This technique, called 'Navashesh', is applicable to any number, but

only while dividing it by 9. It has a wide range of applications, to

check humongous multiplications and additions.

Another technique is finding the square of a number ending in 5. For

example, for squaring 85, all you have to do is take the square of

5, i.e. 25, at the end, and multiply 8 by the next arithmetic digit,

9 (8x9=72) and the answer is 7225
